PCM6xx0Q1EVM-PDK Evaluation Module

2.2.2

Onboard Microphone Input

For the onboard microphone input configuration (shown in

), the PCM6xx0Q1 records the audio

captured from the microphones located on the bottom edge of the board. MICBIAS is used to power the
onboard microphone, so header J27 must be shorted. There must not be any connections to J1 while the
onboard microphone is used to preserve the performance of the microphone. J2 can be used for an
external electret microphone; however this architecture may require the bias resistors R4 and R2 be
changed to optimize microphone performance.
