The 16-bit resolution and Sigma Delta architecture put it in the consumer-audio tier, good for USB speakers, headsets, sound cards, and conference-room peripherals. The 28-SSOP package is a surface-mount footprint that sits on a standard PCB without needing a BGA reflow profile. ## SNR and dynamic range — the audio quality numbers that matter The ADC path delivers 89 dB SNR and 89 dB dynamic range; the DAC path delivers 96 dB SNR and 93 dB dynamic range. ## Supply and temperature range Both analog and digital supplies run from 3.1 V to 3.5 V. The operating temperature range is -25°C to 85°C. ## Lifecycle and sourcing reality The PCM2900BDB-BB is listed as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy clock ticking.","metaTitle":"PCM2900BDB-BB Stereo Audio USB Codec, 16-bit, 28-SSOP","metaDescription":"PCM2900BDB-BB Stereo Audio codec from Texas Instruments.
