DESCRIPTION
Analog interface circuit with internal reference.
Also a plug-in replacement for TLC32041.
Analog interface circuit without internal
reference
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.
