TLC320AD50CPT

Product Summary

The TLC320AD50CPT is a kind of general-purpose analog interface circuit for V.34+ modem and business audio applications. The device provides high-resolution signal conversion from digital-to-analog (D/A) and from analog-to-digital (A/D) using oversampling sigma-delta technology. It includes a pair of 16-bit synchronous serial conversion paths (one for each direction) and includes an interpolation filter before the DAC and a decimation filter after the ADC. Other overhead functions on the chip include timing (sample rate, FSD delay) and control (programmable gain amplifier, PLL, communication protocol, etc.).
