PCM2904DBR Description

Short technical summary and product information.

The Texas Instruments PCM2904DBR is a stereo audio CODEC designed for USB 1.1 applications. It integrates a full-speed USB interface, supporting both adaptive mode for playback and asynchronous mode for recording. This device features two 16-bit Analog-to-Digital Converters (ADCs) and two 16-bit Digital-to-Analog Converters (DACs), providing a maximum sampling rate of 48 kHz for both.

 

Electrical characteristics include a typical operating voltage range of 4.35V to 5.25V. The ADCs offer a Signal-to-Noise Ratio (SNR) of 89 dB and a dynamic range of 89 dB, with a THD+N of 0.01%. The DACs provide an SNR of 96 dB, a dynamic range of 93 dB, and a THD+N of 0.005%. The CODEC operates within a temperature range of -25°C to 85°C.

 

Packaged in a 28-pin SSOP, the PCM2904DBR is designed for surface mount applications. Its functionality includes Human Interface Device (HID) control for volume and mute, making it suitable for various audio interface solutions. This part is distinct from the PCM2906, which includes S/PDIF output.
