SPH0645LM4H-1

I2S Output Digital Microphone

The SPH0645LM4H-1 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 microcontrollers.

Saving the need of an external audio codec, the SPH0645LM4H-1 is perfectly suitable for portable applications where size and power consumption are a constraint.

Typical Applications

  • Small portable devices: wearables
  • Set-top boxes: TV, gaming, remote controllers
  • Smart home devices, Internet of Things, Connected equipment

Product features

  • Flat Frequency Response
  • RF Shielded
  • Supports Dual Microphones
  • Ultra-Stable Performance
  • Standard SMD Reflow
  • Omnidirectional
  • Bottom-Ported Microphone
