Introduction
The SPH0645LM4H-B is a miniature, low-power, bottom-port microphone with I2S digital output. The solution includes a proven high-performance SiSonic acoustic sensor, a serial ADC, and an interface that conditions the signal into industry-standard 24-bit I2S format. The I2S interface simplifies system integration, allowing direct interconnection with digital processors, application processors, and microcontrollers. Requiring no external audio codec, the SPH0645LM4H-B is ideal for portable applications where size and power consumption are critical.
