TIPCM5122
Overview
The PCM5122 is a stereo audio digital-to-analog converter (DAC) that supports resolutions up to 32 bits and 384kHz sampling rates. It features an integrated miniDSP for hardware-based audio processing and provides 2.1Vrms ground-centered outputs, eliminating the need for bulky DC-blocking capacitors.
Why Choose This Part
The device features a hardware-based volume control and a flexible miniDSP for custom digital filter designs. Its ground-centered output stage simplifies the analog front-end by removing the requirement for output coupling capacitors, reducing PCB footprint and improving low-frequency response.

Key Specifications
Getting Started
To evaluate the part, Texas Instruments offers the PCM5122EVM-U evaluation module which connects via USB. For firmware development, the PurePath Console software allows engineers to configure the miniDSP, while I2C or SPI can be used to manage the internal registers from any standard MCU or SBC.
