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.
