USER GUIDE SiSonic FLEX Evaluation Kit KAS-33100-001 Contents Digital to Analog Converter DAC PCB Mic-On-Flex Assemblies 10 Total 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 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. 2012 Knowles Electronics USER GUIDE SiSonic FLEX Evaluation Kit 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. 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. 3.5mm Headphone Jack 2.5mm Power Supply Jack Input Voltage 100-240V ~0.4A, 50-60Hz Output Voltage +12V 6-Pin Edge Connector 2012 Knowles Electronics Figure 1 2 USER GUIDE SiSonic FLEX Evaluation Kit KAS-33100-001 Digital & Analog Adapter PCBs • The digital and analog adapters are for both analog and digital microphones. Note See the product datasheet for specifications: • Analog microphones will need to be powered and connected externally.
