com initiated by either an I2C command or by a logic level control on a separate input pin.
The calibration sequence compensates for gain and frequency response variations of the microphones used with the LMV1088, eliminating the need to use expensive matched microphone sets.
The calibration data is stored in the internal EEPROM memory.
The LMV1088 has two differential input microphone amplifier channels plus far field noise suppression (FFNS) processing circuitry.
