| Description | In this technote, we discuss MEMS microphone array measurements and use a test board with 16 PDM mics configured in a line array to illustrate the typical measurements. The technote specifically details the test procedure, and important considerations, for measuring key performance factors of the microphone array using a PDM 16-equipped APx525 audio analyzer. The technote has also been updated to reflect the multiple simultaneous input types feature (multi-input) added in the version 6.0 release of APx software. Visit the APx PDM 16 Module Page |
