MT102

Digital microphone is becoming popular in Cellphone for stereo and multi microphones solutions. The output signal from the stereo digital microphones is encoded by Pulse Density Modulation (PDM). The MT102 is a D/A converter which separates the PDM digital signals into two channel analog signals. The analog signals are then input into the audio analyzer (such as VA-Audio system) for analysis. The MT102 works with the PDM signals from one or two digital microphones.
