TechNote: Testing Microphone Arrays with the APx PDM 16 Module
March 16, 2020
This Audio Precision technote discusses MEMS microphone and mic array measurements, including important considerations and a detailed example test procedure.
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.
Stricter guidelines imposed by version 3 of the IEC standard for harmonic current emissions push designers to embrace power-factor-correction methodologies.
The flyback topology is a versatile, widely used, switched-mode power-supply design with some interesting characteristics that brings performance and BOM advantages to many applications...
