ICS-43432

The ICS43432 is a high performance, low power, digital output, omnidirectional MEMS microphone with a bottom port. The complete ICS43432 solution consists of a MEMS sensor, signal conditioning, an analog to digital converter, decimation and antialiasing filters, power management, and an industry standard 24bit IS interface. The IS interface allows the ICS43432 to connect directly to digital processors, such as DSPs and microcontrollers, without the need for an audio codec in the system.

The ICS43432 has a high SNR making it an excellent choice for far field applications. The ICS43432 has a wideband frequency response, resulting in natural sound with high intelligibility. The sensitivity tolerance of the ICS43432 is ±1 dB, which enables high performance microphone arrays without the need for system calibration.
