ADC, Audio 32 b 8k ~ 192k I2S 20-WQFN (3x3) The PCM1822 is a high-performance, Burr-Brown™ audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to two analog channels. The device supports single-ended and differential line and microphone inputs with a 1-VRMS full-scale signal. The device integrates a phase-locked loop (PLL), a DC removal high-pass filter (HPF), and supports sample rates up to 192 kHz. The device supports time-division multiplexing (TDM) or I2S audio formats, selectable with the hardware pin level. Additionally, the PCM1822 supports master and slave mode selection for the audio bus interface operation. These integrated high-performance features, along with the ability to be powered from a single supply of 3.3 V, make the device an excellent choice for costsensitive, space-constrained audio systems in far-field microphone recording applications. The PCM1822 is specified from –40°C to +125°C, and is offered in a 20-pin WQFN package.
