A2TPMI

DESCRIPTION

The PerkinElmer A2TPMI is a versatile infrared thermopile sensor with an integrated configurable ASIC

for signal processing and ambient temperature compensation. This integrated infrared module senses

the thermal radiation emitted by objects and converts this to a analog voltage.

The A2TPMI can be delivered fully factory calibrated and adapted to the customer specification, as well

as customer programmable via the serial interface. In the pre-calibrated version, only three pins are

necessary for operation: object output voltage, 5V supply voltage, and ground.

As described in this specification, the temperature accuracy of the fully adjustable integrated circuit out-

performs that of the previous PerkinElmer thermopile modules with discrete components on pcb, be-

cause the A2TPMI features an offset correction of the amplifier and a factory calibrated ambient tem-

perature sensor. This makes the A2TPMI a versatile, compact and high precision device.

Due to the internal digital signal processing and 8 bit resolution of the internal control registers the

A2TPMI has improved accuracy for adjustment and improved performance. EPROM technology allows

unlimited changing of the configuration.

For amplification of the highly sensitive thermopile signal in the micro- to millivolt range, a high resolu-

tion programmable low noise chopper amplifier is provided. An adjustable high precision ambient tem-

perature sensor followed by a signal processor, offers an accurate compensation signal with polynomial

characteristics that perfectly matches to that of the thermopiles output. Adding of these signals results in

an ambient independent object temperature signal over a large temperature range, which still can be

adapted / scaled to customer needs due to flexible offset and postgain adjustment facilities of the de-

vice.

The two configurable comparators of the A2TPMI, that can alternatively be used, enhance the function-

ality. This allows to employ the A2TPMI as an temperature dependent switch for alarm purposes.

Threshold temperatures and the hysteresis is free programmable for both comparators.

Due to integration of sensor and electronic in a compact TO 39 housing, the A2TPMI is robust and

insensitive to environmental influences like pcb contamination (leakage currents), humidity and electro-

magnetic interference.

A2TPMI

General Description

THERMOPILE SENSOR

The signal voltage, generated by the infrared radiation-sensitive thermopile sensor, is preamplified by a

programmable choppered amplifier with 8 bit resolution.

Due to the principle of thermopile temperature measurements, the thermopile voltage can be positive or

negative depending if the object temperature is higher or lower than the ambient temperature of the

A2TPMI. In order to allow signal processing of negative voltages with a single supply system, all internal

signals are related to an internal voltage reference (Vref) of nominal 1.225 V, which serves as a virtual

analog ground.

For offset voltage trimming of the thermopile amplification path, the preamplifier is followed by a

programmable trimming stage generating an offset voltage with a resolution of 8 bit.

The thermopile voltage shows a non-linear output characteristic versus the object temperature.

AMBIENT TEMPERATURE SENSOR

The temperature of the A2TPMI, respectively the thermopile sensor, is detected by an integrated tem-

perature sensor. This signal will be amplified and signal processed in order to match the reverse char-

acteristics of the amplified thermopile curve, to realize an optimum of ambient temperature compensa-

tion after adding the two signals. The characteristics of the temperature sensor signal is adjustable.

This adjustment is part of the ASIC production process and will be provided by PerkinElmer. Thus the

characteristics of the A2TPMI ambient temperature signal V

Tamb

is always provided fully calibrated.

AMBIENT TEMPERATURE COMPENSATION

The thermopile sensor converts the temperature radiation of an object surface to an electrical signal by

means of thermocouples (Seebeck effect). The sensor output voltage is caused by the temperature

difference between radiation heated (hot) junctions and cold junctions with a good thermal contact to the

housing.

In order to deliver an output signal which is only dependent on the object temperature, any change of

housing (ambient) temperature has to lead to an appropriate output signal correction.

For temperature compensation, the amplified thermopile- and temperature reference signals (V

Tamb

int)

are added in an adding amplifier stage. The amplification is adjustable in a wide range according to

application / customer requirements.

The ambient temperature compensated and amplified signal is supplied to the output V

Tobj

. The tem-

perature reference signal or alternatively the bandgap reference voltage is available on a second output

pin V

Tamb

. Both outputs are short circuit stable .

A2TPMI

CONTROL UNIT / SERIAL INTERFACE

The operation characteristics of the A2TPMI have to be configured with a set of internal random access

registers. All parameters / configurations are permanently stored in E2PROM in parallel, Configuration

is usually done during factory calibration and does not need any user input.

The control unit offers via serial interface access to all the registers, i.e. the internal parameters of the

A2TPMI. The serial interface is a two wire bi-directional synchronous (SDAT, SCLK) type. A2TPMI sen-

sors are in general factory calibrated and therefore there is no need to use the serial interface for stan-

dard applications.

The SDAT- / SCLK pins are internally pulled up to VDD and can be left unconnected. If the SDAT /

SCLK pins will be connected in the application, ensure signal conformity to the serial interface specifica-

tion. Subsequent undefined signals applied to these pins, may change the configuration and lead to

malfunctioning of the sensor.

For detailed information about the serial interface refer to application note: A2TPMI Serial Interface de-

scription, or contact PerkinElmer application support.

OUTPUT CONFIGURATION

The A2TPMI offers various output configurations, which can be configured via the serial communication

interface by means of integrated analog switches. For each output it can be individually selected

whether the output operates in ‘Analog mode’ or in ‘Comparator mode’.

In ‘Analog mode’ the output signal represents the measured IR radiation, respectively the temperature

as an analog DC voltage.

In ‘Comparator mode’ the measured IR radiation, respectively the temperature is compared to a pro-

grammed threshold. For slowly changing signals an additional hysteresis can be configured. If the

measured signal is above the threshold, +5VDC (logical high) is applied to the output. If the measured

signal is below the threshold, 0VDC (logical low)is applied to the output.

For detailed information about the output configuration refer to application note: A2TPMI Serial Interface

description, or contact PerkinElmer application support.

Application Information

AMBIENT TEMPERATURE COMPENSATION

Because of many physical effects, that influence the non-contact temperature measurement based on

infrared radiation, it is difficult to meet the best initial adjustment for a specific application. Therefore

some deviations might be found at first measuring. For all applications the optimized solution can be

prepared and fixed based on the measurement in the application environment. PerkinElmer is pleased

in providing you assistance to find the conditions, which deliver the highest accuracy in your application.

The temperature compensation is only working well within a certain ambient temperature range, limited

by different device parameters of the thermopile sensor and the temperature reference sensor. The

following diagram shows a typical characteristics and is only an example for better understanding of the

principle compensation curve. The curve shows the deviation for a correct working of a compensated

module.

The compensation of the module sample in the diagram is adjusted to the best fitting at 20°C to 80°C

ambient temperature, but the curve can be shifted in the whole ambient temperature range through the

change of A2TPMI parameters.

MEASUREMENT TOLERANCE

The temperature error of the A2TPMI depends on several factors like the emissivity, object temperature,

object size to spot size relation, temperature gradients over the sensor housing in the environment,

device tolerances and the optimal adjustment of the ambient temperature compensation.

The accuracy as specified under V

characteristics is based on theoretical calculation as

well as on statistical evaluation results. The PerkinElmer quality system ensures that all A2TPMIs are

calibrated and tested under a certain test conditions in order to guarantee these specifications.

However, due to the nature of infrared remote temperature measurements there might occur limits ex-

ceeding or deviations in specific application environments. In this case please contact the PerkinElmer

application support to help you solving the problem.

OUTPUT LOAD

Capacitive loads which are applied directly to the outputs reduce the loop stability margin. Values of

100 pF can be accommodated. Resistive load for the outputs should be held as small as possible (i.e. a

large load resistance, R

load

> 50 kW has to be used) in order to avoid an impact on the temperature sig-

nal due to self heating of the module.

RESPONSE TIME

The response time to an object temperature jump depends on the time constant

of the thermopile and

the signal processing time of the A2TPMI. The processing of the thermopile signal has a latency time

LATCHUP AVOIDANCE

Junction isolated CMOS circuits inherently include a parasitic 4 layer (PNPN) structure which has char-

acteristics similar to a thyristor (SCR). Under certain circumstances this junction may be triggered into a

low impedance state, resulting in excessive supply current, which can thermally destroy the circuit.

To avoid this condition, no voltage greater than 0.3 V beyond the supply rails should be applied to any

pin. In general the ATPMI supplies must be established either at the same time or before any signals

are applied to the inputs. If this is not possible the drive circuits must limit the input current flow to

maximum 5mA to avoid latchup. In general the device has to be operated with a 100 nF capacitor in

parallel to the power supply.

SOLDERING

The TPMI is a lead-free component and fully complies with the ROHS regulations, especially with exist-

ing roadmaps of lead-free soldering. The terminations of the TPMI sensor consist of nickel plated Kovar

and gold finish. Hand soldering is recommended.

Liability Policy

The contents of this document are subject to change without notice. Customers are advised to consult

with PerkinElmer Optoelectronics sales representatives before ordering.

Customers considering the use of PerkinElmer Optoelectronics thermopile devices in special applica-

tions where failure or abnormal operation may directly affect human lives or cause physical injury or

property damage, or where extremely high levels of reliability are demanded, are requested to consult

with PerkinElmer Optoelectronics sales representatives before such use. The company will not be re-

sponsible for damage arising from such use without prior approval.

As any semiconductor device, thermopile sensors or modules have inherently a certain rate of failure. It

is therefore necessary to protect against injury, damage or loss from such failures by incorporating safety

design measures into the equipment.
