ADA4096-2:  30 V, Micropower, Overvoltage Protection, RRIO Dual Op Amp

Product Details

Product Status:Recommended for New Designs

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 ADA4096-4 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 (−40°C to +125°C) and is part of the growing selection of 30 V, low power op amps from Analog Devices, Inc.
