3 Description
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.
