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.
