GENERAL DESCRIPTION
The ADA4096 family of operational amplifier features micro-
power operation and rail-to-rail input and output ranges. The
extremely low power requirements and guaranteed operation
from 3 V to 30 V (±1.5 V to ±15 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 applications. The amplifier can drive capacitive loads up
to 200 pF without oscillation.
The ADA4096 has overvoltage protection inputs that allow the
voltage input to exceed 32V above and below the supply rails
without damage, glitching, or phase reversal, making the device
ideal for robust industrial applications.
The ADA4096 are specified over the extended industrial
(–40°C to +125°C) temperature range. The dual ADA4096-2 is
available in 8-lead LFCSP (2x2) and 8-lead MSOP packages.

Performance specifications are not guaranteed during overvoltage
conditions.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
