3 Description
The PCM1822-Q1 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-Q1
supports master and slave mode selection for the
audio bus interface operation. These integrated highperformance
features, along with the ability to be
powered from a single supply of 3.3 V, make the
device an excellent choice for cost-sensitive, spaceconstrained
audio systems in far-field microphone
recording applications.
The PCM1822-Q1 is specified from –40°C to +125°C,
and is offered in a 20-pin WQFN package.
