Printed circuit board microphone SPH0645LM4H-B

MEMSminiaturedigital

The SPH0645LM4H-B is a miniature, low power, bottom port microphone with an I2S digital output. 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-bit I2S format. The I2S interface simplifies the integration in the system and allow direct interconnect to digital processors, application processors and microcontrollerss. 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.
