The ICS-43432 is a low-noise MEMS microphone with an I2S 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 I2S 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.
Digital I2S Output Low Current Consumption: 1 mA SNR: 65 dBA 116 dB Maximum SPL (Acoustic Overload Point) Sensitivity Tolerance: ±1 dB Sensitivity: –26 dB Wide Frequency Response from 50 Hz to 20 kHz High Power Supply Rejection: −80 dB RoHS/WEEE Compliant Compatible with Sn/Pb and Pb-Free Solder Processes Dimension: 4mm ´ 3mm ´ 1mm
