description

The TLC32044 and TLC32045 are complete

analog-to-digital and digital-to-analog input and

output systems on single monolithic CMOS chips.

The TLC32044 and TLC32045 integrate 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.

The devices offer numerous combinations of

master clock input frequencies and conversion/

sampling rates, which can be changed via digital

processor control.
