description

The TLC32040 and TLC32041 are complete

analog-to-digital

and

digital-to-analog

input/

output systems, each on a single monolithic

CMOS chip. This device integrates a bandpass

switched-capacitor antialiasing input filter, a

14-bit-resolution

A/D

converter,

four

microprocessor-compatible serial port modes, a

14-bit-resolution D/A converter, and a low-pass

switched-capacitor output-reconstruction filter.
