Typical Applications: Small portable devices: wearables, Set-top boxes: TV, gaming, remote controllers, Smart home devices, Internet of Things, Connected equipment. High SNR of 65dB(A), Low Current of typ. 600µA , I2S Output: Direct attach to µP Multi modes: standard >1MHz. The I2S interface simplifies the integration in the system and allow direct interconnect to digital processors, application processors and microcontroller. Saving the need of an external audio codec, the SPH0645LM4H-B is perfectly suitable for portable applications where size and power consumption are a constraint. The solution consists of a proven high performance SiSonic acoustic sensor, a serial Analog to Digital convertor, and an interface to condition the signal into an industry standard 24 bits I2S format. The SPH0645LM4H Digital Microphone Sensor Module is a miniature, low power, bottom port microphone with an I2S digital output.
