charging. Their dynamic performance, including 27 nV/√Hz voltage noise density, recommends them for battery-powered audio applications. Capacitive loads to 200 pF are handled without oscil ation. The ADA4096-2 and ADA4096-4 have overvoltage protection inputs and diodes that al ow the voltage input to extend 32 V 146 above and below the supply rails, making this device ideal for
