Model DCC-1448 and PQC-3048 - Digital Microphone Brochure

Listen offers 2 MEMS digital microphone measurement interfaces from Portland Tool & Die, the laboratory-grade DCC-1448 and the low cost PQC-3048 for production line use. The DCC-1448 and PQC-3048 interface your MEMS microphone to the SoundCheck test system, converting the 1-bit PDM output of a Digital MEMS microphone to the 24-bit, 48kHz PCM signal accepted by audio test systems. This enables measurement of typical microphone characteristics such as frequency response, sensitivity and directivity.
