DEMO MANUAL DC1338B
LTC2990 I
2
C Temperature
Voltage and Current Monitor
DESCRIPTION
Demonstration circuit 1338B features the LTC
®
2990, a
high performance temperature, voltage and current moni-
tor that uses I
2
C for communication. It offers submillivolt
resolution and 1% current and 1°C temperature measure-
ment accuracy.
DC1338B is a member of Linear Technology’s QuikEval™
family of demonstration boards. It is designed to allow easy
evaluation of the LTC2990 and may be connected directly
to the target application’s analog signals while using the
DC590 USB Serial Controller board and supplied software
to measure performance. Exposed ground planes allow
proper grounding to prototype circuitry. After evaluating
with Linear Technology’s software, the I
2
C lines can be
connected to the end application’s processor/controller
for development of the serial interface.
Design fi les for this circuit board are available at
/demo

QUICK START PROCEDURE
Connect DC1338B to a DC590 USB serial controller using
the supplied 14 conductor ribbon cable. Connect DC590
to host PC with a standard USB A/B cable. Run the evalu-
ation software supplied with DC590 or downloaded from
/software. The correct program
will be loaded automatically. Click the COLLECT button to
start reading the input voltage (COLLECT button becomes
PAUSE after collection has been initiated). Details on
software features are documented in the control panel’s
help menu.
