The PMM-3738-VM1000-R is a low noise, low part-

to-part variation, high dynamic range, single ended

analog output piezoelectric MEMS microphone.

This microphone consists of a piezoelectric sensor

and circuitry to buffer and amplify the output.

The PMM-3738-VM1000-R has a small 3.76 mm X

2.95 mm X 1.1 mm package. This microphone is

reflow solder compatible without sensitivity

degradation.
