ICS‐43432 Low‐Noise Microphone with I2S Digital Output GENERAL DESCRIPTION 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 allows the 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.
