Abstract: The drawbacks of the use of embedded digital microphones in electronic apparatuses is overcome by a digital microphone destined to be embedded in the apparatus that contemplates the presence of an auxiliary line-in terminal or terminals in the packaged digital microphone device, to which a remote analog microphone (MIC2) may be connected.
The result is that the use of an external (remote) analog microphone (MIC2) does not require a dedicated additional analog-to-digital converter. Such a line-in function may even be duplicated even for more than one external analog microphone.
