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.
