PCMx140Q1EVM-PDK Evaluation Module
Description
The ADCx140EVM-PDK is an evaluation module
(EVM) that allows the user to test the
capabilities of the PCMx140-Q1 family of devices,
which is a quad-channel, high-performance audio
analog-to-digital converter (ADC). The PCMx140-
Q1 is intended for voice-activated systems,
professional microphones, audio conferencing,
portable computing, communication, entertainment,
and automotive applications. PCMx140Q1EVM-PDK
is paired with the AC-MB (included in the kit), a
flexible motherboard that provides power, control, and
digital audio data to the EVM.
Get Started
1. Order the EVM from the
product page.
2. Download the latest PCMx140-Q1 data sheet.
3. Request access and download PPC3 GUI and the
associated PCMx140Q1EVM-PDK app from the
