ICS43432: Low-Noise Microphone with I 2S 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.
