The PCM1809 is a low power 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 2VRMS full-scale differential signal. The device integrates a phase-locked loop (PLL), a DC removal high-pass filter (HPF), and supports sample rates up to 192kHz. The device supports time-division multiplexing (TDM) or I2S audio formats, selectable with the hardware pin level. Additionally, the PCM1809 supports Controller and target mode selection for the audio bus interface operation. These integrated features, along with the ability to be powered from a single supply of 3.3V, make the device an excellent choice for cost-sensitive, space-constrained audio systems in microphone recording applications.

The PCM1809 is specified from –40°C to +105°C, and is offered in a 20-pin WQFN package.
