It handles both analog-to-digital and digital-to-analog conversion with 16-bit resolution. The codec includes two ADCs and two DACs, supporting stereo capture and playback over a USB connection without requiring a separate audio controller or driver development for standard operating systems. Sigma-delta modulation is employed for the conversion stages, which contributes to the dynamic range figures: 89 dB for the ADC path and 93 dB for the DAC path, with corresponding signal-to-noise ratios of 89 dB and 96 dB respectively. ## Supply rail and temperature range This simplifies the power tree in USB-powered designs where the bus voltage is regulated down to 3.3 V. ## 28-SSOP package and board integration The supplier device package is specified as 28-SSOP, confirming the footprint matches standard SSOP-28 land patterns.","metaTitle":"PCM2903CDBR USB Stereo Audio Codec, 16-bit, 28-SSOP","metaDescription":"PCM2903CDBR USB stereo audio codec, 16-bit resolution, 89/96 dB SNR, 28-SSOP.
