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.
