Description
The K AS-33100 -001 evaluation kit allows for simple and easy evaluation of
SiSonic™ MEMS microphones. This evaluation system can be used to
evaluate up to two channels of audio for Digital (Page 6) MEMS microphones
along with one channel of audio for Analog MEMS microphones (Page 8).
One DAC PCB board, three Adapter PCBs, and ten Mic-On-Flex Assemblies
are included in the evaluation kit. The power supply (AC Adapter) and headset
are purchased separately.

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.
