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.
