Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ICS‐43432 is a digital I²S output bottom port microphone. The complete ICS‐43432 solution consists of a MEMS sensor, signal conditioning, an analog‐to‐digital converter, decimation and anti‐aliasing filters, power management, and an industry standard 24‐bit I²S interface. The I²S interface allowsthe ICS‐43432 to connect directly to digital processors,such as DSPs and microcontrollers, without the need for an audio codec in the system.   

The ICS‐43432 has a high SNR of 65 dBA and a wideband frequency response. The sensitivity tolerance of the ICS‐43432 is ±1 dB, which enables high‐performance microphone arrays without the need for system calibration. 

The ICS‐43432 is available in a small 4 mm × 3 mm × 1 mm surface‐mount package.
