PCM2902E Description

Short technical summary and product information.

The Texas Instruments PCM2902E is a stereo audio CODEC designed for USB 1.1 applications. It integrates full-speed transceivers compliant with the USB 1.1 specification and supports both adaptive mode for playback and asynchronous mode for recording.

 

This device features two 16-bit delta-sigma Analog-to-Digital Converters (ADCs) and two 16-bit delta-sigma Digital-to-Analog Converters (DACs). The ADCs offer a sampling rate up to 48 kHz with THD+N of 0.01% and SNR of 89 dB. The DACs also support sampling rates up to 48 kHz, with THD+N of 0.005% and SNR of 96 dB. It includes S/PDIF input and output for digital audio transmission.

 

The PCM2902E operates from a single 5V power supply, typically derived from the USB bus. It supports analog inputs and outputs, with integrated antialiasing filters for the ADC and analog low-pass filters for the DAC. Multifunction capabilities include Human Interface Device (HID) control for volume and mute functions, along with a suspend flag.

 

Packaged in a 28-pin SSOP, the PCM2902E is suitable for applications such as USB audio speakers, headsets, monitors, and interface boxes. It is important to note that this part is not recommended for new designs.
