MAX9814ETD+T
Brand: Analog Devices
The MAX9814ETD+T is a microphone amplifier that combines a 30 nV/√Hz low-noise preamp, automatic gain control with 40/50/60 dB pin-selectable range, and a built-in 2.0 V microphone bias generator in one 14-pin TDFN-EP. Fully analog SHDN/GAIN/A-R/TH/CT control pins set behavior without firmware, and 0.04% typical THD+N keeps audio clean across the AGC range from a 2.7 V to 5.5 V supply.
