Product Summary

The TLC32044CN is a voice-band analog interface circuit. The TLC32044CN 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. The TLC32044CN offers numerous combinations of master clock input frequencies and conversion/sampling rates, which can be changed via digital processor control.
