MP23AB02BTR

MP23AB02BTR Description

The MP23AB02BTR from STMicroelectronics is a high-performance MEMS (Silicon) omnidirectional analog microphone designed for precision audio capture in compact electronic devices. Operating within a 1.6V to 3.6V voltage range and consuming just 220 µA, it delivers a 64dB signal-to-noise ratio (S/N Ratio) with a frequency response of 20Hz–20kHz, making it suitable for high-fidelity audio applications. Its bottom-port design and ultra-small 3.35mm x 2.50mm x 1.08mm form factor enable seamless integration into space-constrained designs. Although marked as Obsolete, it remains a reliable choice for legacy systems requiring low-power, high-quality analog audio input.
