The INMP522 is an omnidirectional, bottom-ported, digital output MEMS microphone with high performance, ultra-low noise, and low power. The INMP522 has a sensitivity tolerance of ±1 dB from part to part, making it ideal for microphone array and beamforming applications.
The INMP522 consists of a MEMS microphone element and an impedance converter amplifier followed by a fourth-order S-? modulator. The digital interface enables the pulse density modulated (PDM) output of two microphones to be time multiplexed on a single data line using a single clock. The INMP522 is function- and pin-compatible with the INMP521 and INMP421 microphones, providing an easy upgrade path.
