GENERAL DESCRIPTION
The ADA4096-2 features a unique input stage that allows the
input voltage to exceed either supply safely without any phase
reversal or latch-up; this is called overvoltage protection, or OVP.
The ADA4096 operational amplifier features micropower
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 dual ADA4096-2 is available in 8-lead LFCSP (2 mm × 2 mm)
and 8-lead MSOP packages. The ADA409x family is specified
over the extended industrial temperature range (−40°C to +125°C)
and is part of the growing selection of 30 V, low power op amps
from Analog Devices, Inc. (see Table 1).
The ADA4096-2 has overvoltage protection inputs and diodes
that allow the voltage input to extend 32 V above and below
the supply rails, making this device ideal for robust industrial
applications.
