PCM1841-Q1 Evaluation Module
Description
The PCM1841Q1EVM-PDK evaluation module (EVM)
allows the user to test the capabilities of Texas
Instruments' PCM1841-Q1 device. The PCM1841-Q1
is a high-performance, Burr-Brown
digital converter (ADC) that supports simultaneous
sampling of up to four analog channels. The device
supports differential line and microphone inputs with
2-VRMS 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), I 2S, or left-justified (LJ)
audio formats, selectable with the hardware pin level.
