PCM2903CDBR Description

Short technical summary and product information.

The Texas Instruments PCM2903CDBR is a single-chip, stereo audio CODEC designed for USB connectivity. It integrates a full-speed USB protocol controller, compliant with USB 2.0 specifications, enabling both adaptive playback and asynchronous recording modes.

 

This CODEC features 16-bit delta-sigma ADCs and DACs, supporting various sampling rates up to 48 kHz. The analog performance includes a THD+N of 0.01% for the ADC and 0.005% for the DAC, with Signal-to-Noise Ratios (SNR) of 89 dB and 96 dB respectively. Dynamic range figures are 89 dB for ADCs and 93 dB for DACs.

 

The PCM2903CDBR operates from a single 3.3V power supply and includes an on-chip clock generator. It supports S/PDIF input/output and includes Human Interface Device (HID) functions for volume and mute controls. The device is housed in a 28-pin SSOP package, suitable for surface mounting.

 

With its integrated USB interface and comprehensive audio conversion capabilities, the PCM2903CDBR is well-suited for applications requiring direct audio connection to USB hosts, such as portable audio devices, multimedia peripherals, and embedded audio systems.
