TIPCM5242
Overview
The Texas Instruments PCM5242 is a high-performance, 32-bit, 2-channel audio DAC designed for professional audio applications. It features DirectPath ground-biased outputs, eliminating the need for DC blocking capacitors, and an integrated negative charge pump. This DAC supports various PCM data formats including I2S, Left-Justified, Right-Justified, and TDM, and can be configured via hardware or software.
Why Choose This Part
Engineers choose the PCM5242 for its differential DirectPath ground-biased outputs, which simplify output stage design by removing the need for DC blocking capacitors. It offers market-leading low out-of-band noise, contributing to a clean audio signal. The integrated high-performance audio PLL simplifies clocking schemes by allowing internal SCK generation from a BCK reference.
