The keyword to search for is "digital mems", and of course we are talking individual parts to place on PCB, not the consumer device. Here is one random example: [0]. Somewhat expensive at $1 ea, but that's what you pay for US manufacturer.

This microphones take 2.4 MHz clock and return PDM (pulse density modulation) signal. Does not seem very convinient for old-school analog electronic circuits, but it's pretty trivial to interface with any micro with pulse counter hardware.

And presumably the audio won't have any hum or interference from nearby radio transmitters, which is especially useful in cell phones.
