TIPCM5142PWR
Overview
The PCM5142PWR is a high-performance stereo audio DAC featuring an integrated programmable miniDSP and a negative charge pump. It supports resolutions up to 32 bits and 384kHz sampling rates while eliminating the need for bulky DC-blocking capacitors at the output. The device operates from a single 3.3V supply and includes an intelligent muting system to prevent pop and click noise during power transitions.
Why Choose This Part
The integrated miniDSP allows for custom signal processing without taxing the host processor, while the ground-centered 2.1VRMS outputs simplify analog front-end design. Its high-performance PLL generates required clocks from a standard BCK, and the fail-safe digital inputs remain high-impedance when the device is unpowered, preventing back-driving issues.

Key Specifications
Getting Started
Evaluate performance using the PCM5142EVM-U development kit, which provides a USB interface for direct connection to a PC. Software configuration and miniDSP programming are handled via TI PurePath Console, allowing for graphical tuning of filters and audio processing blocks over I2C or SPI.
