12-Bit Sampling A/D Converters
s3µs, 5µs or 10µs Sample/Conversion
Time
sStandard ±10V and ±5V Input
sNo Missing Codes Over Temperature
sAC Performance Over Temperature
71.5dB Signal–to–Noise Ratio at Nyquist
85dB Spurious–free Dynamic Range
at 49kHz
–81dB Total Harmonic Distortion at 49kHz
sInternal Sample/Hold, Reference,
Clock, and 3-State Outputs
sLow Power Dissipation: 90mW
s28–Pin Narrow PDIP and SOIC
DESCRIPTION…
The SP85XX Series are complete 12-bit sampling A/D converters using state–of–the–art
CMOS structures. They contain a complete 12–bit successive approximation A/D converter
with internal sample/hold, reference, clock, digital interface for microprocessor control, and
three–state output drivers. Power dissipation is only 90mW. AC and DC performance are
completely specified. Sampling/conversion rates of 3µs, 5µs and 10µs are offered.
