INMP441ACEZ Datasheet PDF - InvenSense

●The INMP441ACEZ is an Omni-directionalMEMS microphone with bottom port and I2S digital output in 9 pin LGA package. This high performance, low power, digital output solution consists of MEMS sensor, signal conditioning, an analogue to digital converter, anti aliasing filters, power management and an industry standard 24bit I2S interface. The I2S interface allows INMP441 to connect directly to digital processors such as DSPs and microcontrollers without the need for an audio codec in system. It has high SNR, making it an excellent choice for near field applications. The INMP441 has flat wideband frequency response resulting in natural sound with high intelligibility.
