Product overview
Description
The IMP23ABSU 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 IMP23ABSU has an acoustic overload point of 130 dBSPL with a typical 64 dB signal-to-noise ratio.
The sensitivity of the IMP23ABSU is -38 dBV ±1 dB @ 94 dBSPL, 1 kHz.
The IMP23ABSU 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.

A MEMS microphone is an electro-acoustic transducer housing a sensor (MEMS) and an application-specific integrated circuit (ASIC) in a single package.
Top port MEMS microphones are designed in a plastic package with a dedicated ground ring around the port hole for ESD robustness. The MEMS are positioned directly beneath the port hole to maximize acoustic performance. Bottom port devices are designed in a metal package to improve product robustness and reliability. The substrate includes capacitance plating to improve RF immunity.
MEMS microphones with Analog output means lower power consumption and a smaller/compact ASIC structure. Digital MEMS microphone includes an ADC to convert the analog signal to a PDM signal thus allowing a robust data transmission and better EMI rejection
