2.4.2 Digital Microphone

The SPH0641LU4H device is suitable for a varying range of applications; it provides a means for sensing sounds (see [2]). The SPH0641LU4H is a low-power microphone with high performance and good RF immunity. The microphone can be operated in the five modes that follow:

  • Powered down mode, VDO = 0 V
  • Sleep mode, VDO ranges from 3.6 V to 1.62 V

    • fCLOCK ≤ 250 kHz

  • Low-power mode, VDO ranges from 3.6 V to 1.62 V

    • 351 kHz ≤ fCLOCK ≤ 815 kHz

  • Ultrasonic mode, VDO ranges from 3.6 V to 1.62 V

    • 3.072 MHz ≤ fCLOCK ≤ 4.8 MHz

  • Standard performance mode, VDO ranges from 3.6 V to 1.62 V

    • 1.024 MHz ≤ fCLOCK ≤ 2.475 MHz
