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.

Handling Instructions
The Piezo MEMS microphone is very robust to harsh environments such as dust and moisture. However, to
avoid mechanical damage to the microphone, we recommend using appropriate handling procedures when
manually handling the parts, or when using pick-and-place equipment. The following guidelines will help to
avoid damage:
Do not apply a vacuum to the bottom side of the microphone. A vacuum pen may be used with care on
the top side only.
Do not apply very high air pressure over the sound port hole.
Do not insert any large particles or objects in the sound port hole. The microphone is resistant to
small particles per IP5X specification.
Do not board wash or clean after the reflow process or expose the sound port to harsh chemicals.
Do not cover the sound port with tape during the solder reflow process.
