TIPCM2902CDBR
Overview
The PCM2902CDBR is a single-chip USB stereo audio codec designed for high-performance audio applications. It integrates two channels of ADC and two channels of DAC with a USB-compliant interface and S/PDIF digital output in a 28-SSOP package. The device is powered by a 3.3V analog supply and operates across a temperature range of -25C to 85C.
Why Choose This Part
This IC simplifies design by integrating a USB 1.1 compliant full-speed protocol controller, eliminating the need for custom firmware. It features high accuracy with 0.005 percent THD+N and includes 5V tolerant I/O for flexible system integration. The SpAct architecture provides low-jitter clock recovery from the USB data stream for improved audio fidelity.
Applications
Key Specifications
Getting Started
Engineers can evaluate the device using Texas Instruments EVMs or by referencing the typical application circuit in the datasheet, which requires minimal external components beyond a crystal and basic decoupling. Since it is a USB class-compliant device, it requires no custom drivers for operation on most modern operating systems.
