  • Fully-differential input/output
  • 2.2 to 5.5 V single supply operation
  • Low power consumption at 20 dB: 1.8 mA
  • Fast start up time at 0 dB: 5 ms typ.
  • Low distortion: 0.1% typ.
  • 40 kHz bandwidth regardless of the gain
  • Active low standby mode function (1 μA max)
  • Low noise 2.0 V microphone bias output
  • Available in flip-chip lead-free package and in QFN24 4 x 4 mm package
  • ESD protection (2 kV)

Applications:

  • Video and photo cameras with sound input
  • Sound acquisition and voice recognition
