Digital MEMS Microphone - ICS-43432, InvenSense
The
ICS-43432
is a low-noise MEMS microphone with an I
2
S digital output. The
InvenSense
digital microphone ICS43432 has fully decimated outputs that allow them to be connected directly into microcontrollers (MCU) and DSPs. The device contains a MEMS sensor, an analog to digital converter, signal conditioning, decimation and anti-aliasing filters along with a 24-bit I
2
S interface.
The digital microphone is bottom ported and has a high signal to noise ratio (SNR) along with a wideband frequency response It is also perfect when an audio codec design is not needed. The applications include wearables, remote controls, teleconferencing systems, gaming consoles, security systems, and microphone arrays.
