GENERAL DESCRIPTION

The ADA4096-2 dual and ADA4096-4 quad operational

amplifiers feature 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 applications. Capacitive loads to 200 pF are handled

without oscillation.

The ADA4096-2 and ADA4096-4 have 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. The ADA4096-2 and ADA4096-4

feature 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 dual ADA4096-2 is available in 8-lead LFCSP (2 mm ×

2 mm) and 8-lead MSOP packages. The ADA4096-2 is available

in 16-lead LFCSP (3 mm × 3 mm) and 14-lead TSSOP

packages. The ADA4096-2W is qualified for automotive

applications and is available in an 8-lead MSOP package.

The ADA409x family is specified over the extended industrial

temperature range of (−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).
