The PCM1841-Q1 is a high-performance, Burr-Brown™
audio analog-to-digital converter (ADC) that supports simultaneous sampling of up to four
analog channels. The device supports differential line and microphone inputs with a
2VRMS full-scale signal. The device integrates microphone bias voltage, a
phase-locked loop (PLL), a DC removal high-pass filter (HPF), and supports sample rates up
to 192kHz. The device supports time-division multiplexing (TDM), I2S, or
left-justified (LJ) audio formats, selectable with the hardware pin level. Additionally, the
PCM1841-Q1 supports controller and target 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 3.3V, make the device an excellent choice for cost-sensitive,
space-constrained audio systems in far-field microphone recording applications.
The PCM1841-Q1 is specified from –40°C to
+125°C and is offered in a 24-pin VQFN package.
