Description

The MP45DT02 is a compact, low-power, top-

port, omnidirectional, digital MEMS microphone.

The MP45DT02 is built with a sensing element

and an IC interface with stereo capability.

The sensing element, capable of detecting

acoustic waves, is manufactured using a

specialized silicon micromachining process to

produce audio sensors.

The IC interface is manufactured using a CMOS

process that allows designing a dedicated circuit

able to provide a digital signal externally in PDM

format.

The MP45DT02 has an acoustic overload point of

120 dBSPL with a best on the market 61 dB

signal-to-noise ratio and -26 dB sensitivity.

The MP45DT02 is available in an SMD-compliant

package and is guaranteed to operate over an

extended temperature range from -30 °C to

+85 °C.

The MP45DT02’s digital output and package size

(1.25 mm thick) make this device the best solution

for laptop and portable computing applications.
