Description
The KAS-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.

  • Page 1 3. Adapter PCBs (Digital and Analog) Description The KAS-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).
  • Page 2 KAS-33100-001 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.
  • Page 3 • The digital and analog adapters are for both analog and digital microphones. Note: See the product datasheet for specifications: http://www.knowles.com/search/product.htm?x_sub_cat_id=3 • Analog microphones will need to be powered and connected externally.
