TLC320AD77CDBRG4

General Purpose Audio Codec 2ADC / 2DAC Ch 28Pin SSOP T/R

Introduction

The TLC320AD77C is a cost competitive stereo analog-to-digital A/D and digital-to-analog D/A 24-bit delta-sigma converter for consumer applications which demand excellent audio performance. It has a wide variety of serial input options including left justified, right justified, IIS, or DSP data formats for 16-, 20-, or 24-bit input/output data. It has an extremely wide range of sampling rates starting at 16 kHz and increasing upwards to 96 kHz. Its internal bandgap design provides a very clean voltage reference. The TLC320AD77C is primarily designed for mini-disks, audio/video receivers, musical instruments, and other end-equipments requiring high-performance digital audio conversion.
