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.
