ICS‐43432

Low‐Noise Microphone with I²S Digital Output

APPLICATIONS

GENERAL DESCRIPTION



Wearables

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.

Microphone Arrays

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.
