Article What low power microphone amplifiers with AGC are available other than the MAX9814?

The MAX9814 is the only microphone amplifier with an integrated AGC circuit.  The MAX9814 has a typical active current of 3mA, which is high in several portable low-power systems.  Since the wake-up time of the MAX9814 is only 60us, the active-low /SHDN pin can be used to drop the current down to <1uA and still power on quickly for most audio applications.
