PCM2906CDB Description

Short technical summary and product information.

The Texas Instruments PCM2906CDB is a stereo audio CODEC designed for USB applications. It offers a 16-bit resolution for both Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs), with a maximum sampling rate of 48kHz for DACs and up to 48kHz for ADCs. The device features an on-chip USB interface compliant with USB 2.0 specifications, supporting both adaptive and asynchronous modes.

 

Key electrical characteristics include a typical operating voltage of 3.3V (3.1V to 3.5V) and bus-powered operation. The ADC performance boasts a Signal-to-Noise Ratio (SNR) of 89 dB and a Total Harmonic Distortion plus Noise (THD+N) of 0.01%. The DAC offers superior performance with an SNR of 96 dB and THD+N of 0.005%. It also includes S/PDIF input/output capabilities.

 

This CODEC is housed in a 28-SSOP package and supports surface mount. It integrates features like an on-chip clock generator, antialiasing filters, and digital high-pass filters for ADCs, along with analog low-pass filters for DACs. The Human Interface Device (HID) function allows for volume and mute controls.
