Digital to Analog Converter (DAC) PCB
The intended use is for the evaluation and test of the Knowles Electronics line of
MEMS Digital PDM (Pulse Density Modulation) microphones.
This board is designed to support R&D activities, and is not intended for
qualification or production test use.
The DAC PCB provides the interface circuitry for two digital microphones.
Power is provided via a standard 2.5mm power jack. A 3.5mm stereo headphone
jack is available for quick verification of audio output.
Note: Please reference Knowles Application Note – MEMS Digital
Microphone Evaluation Board: SP-703 for more information.
