  • Packaged digital microphone device with auxiliary line-in function
    Publication number: 20050207596
    Abstract: A digital microphone device outputs a digital audio signal to a digital signal processing system. The digital microphone device includes an acoustic transducer for producing an analog voltage signal representative of an acoustic signal, and an integrated circuit including an input multiplexer. The input multiplexer has a first analog input coupled to an output of the acoustic transducer, and a second analog input to be connected to an output of a remote external analog microphone providing an analog voltage signal. A variable gain analog signal pre-amplifier is coupled to an output of the input multiplexer.
