GENERAL DESCRIPTION
The
operation and rail-to-rail input and output ranges. The
extremely low power requirements and guaranteed operation
from 3 V to 30 V make these amplifiers perfectly suited to
monitor battery usage and to control battery charging. Their
dynamic performance, including 27 nV/√Hz voltage noise
density, recommends them for battery-powered audio applica-
tions. Capacitive loads to 200 pF are handled without oscillation.
The
that allow the voltage input to extend 32 V above and below
the supply rails, making this device ideal for robust industrial
applications.
