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 ADA4096-2 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.
