描述 Description

The MP45DT01 is a compact low-power

microphone built up with a sensing element and

an IC interface with stereo operation 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 to design a dedicated circuit

able to provide a digital signal to the external

world in PDM format.

The MP45DT01 has an acoustic overload point of

120 dBSPL with 58 dB signal to noise ratio.

The MP45DT01 is available in SMD compliant

package and it is guaranteed to operate over an

extended temperature range from -30 °C to +85 °C.
