MP23AB01DM中文资料High-performance MEMS audio sensor: fully differential analog bottom-port microphone数据手册ST规格书

描述 Description

The MP23AB01DM 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 specialized silicon micromachining process to produce audio sensors.
The MP23AB01DM has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio.
The MP23AB01DM has fully differential output in order to minimize common-mode noise.
The sensitivity of MP23AB01DM is -38 dBV ±3 dB @ (0 dB = 1 V/Pa), 1 kHz.
The MP23AB01DM 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.
