Microphone for noise cancelling applications

26 May 2021 Analogue, Mixed Signal, LSI

The MP23ABS1 from STMicroelectronics is a compact, low-power microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialised silicon micromachining process to produce audio sensors.

The MP23ABS1 has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio, and sensitivity of -38 dBV ±1 dB @ 94 dBSPL, 1 kHz.

The MP23ABS1 is available in a package compliant with reflow soldering and is guaranteed to operate over an extended temperature range from -40°C to +85°C.

Characteristics exhibited by the microphone include single supply voltage operation (1,52-3,6 V), omnidirectional sensitivity, enhanced RF immunity, ultra-flat frequency response, low latency and ultra-low current consumption of 150 μA maximum.
