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.
