Product overview
Description
The MP23DB02MM is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and an IC interface with optional stereo configuration. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to produce audio sensors.The IC interface is manufactured using a CMOS process that allows designing a dedicated circuit able to provide a digital signal externally in PDM format.
The MP23DB02MM offers multiple performance modes enabled by different clock frequency ranges (power-down, low-power and normal mode). The device has a narrow sensitivity range of ±1 dB, high SNR and low distortion for all operative modes.
The MP23DB02MM is available in a bottom-port, SMD-compliant, EMI-shielded package 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
