3 Description

The PCM182(0/1)-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 differential line and

microphone inputs with a 2-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 PCM182(0/1)-Q1 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 PCM182(0/1)-Q1 is specified from –40°C to

+125°C, and is offered in a 20-pin WQFN package.
