GENERAL DESCRIPTION

The ADA4099-2BCHIPS is a robust, precision, rail-to-rail input and

output dual-channel operational amplifier with inputs that operate

from −VS to +VS and beyond, which is referred to in this data sheet

as Over-The-Top™. The device features an offset voltage of ±12 μV,

an input bias current (IB) of ±4 nA, and can operate on supplies that

range from 3.15 V to 50 V. The ADA4099-2BCHIPS draws 1.65 mA

of supply current per channel.

The ADA4099-2BCHIPS Over-The-Top input stage has robust input

protection features for abusive environments. The inputs can tolerate

up to 80 V of differential voltage without damage or degradation

to dc accuracy. The operating input common-mode range extends

from rail-to-rail and beyond, up to 70 V > –VS, independent of the

+VS supply.

The ADA4099-2BCHIPS is unity-gain stable and can drive loads

requiring up to 20 mA per channel. The device can also drive

capacitive loads as large as 100 pF. The amplifier is available with

low power shutdown per channel.

The ADA4099-2BCHIPS is specified at +25°C but is functional

over the extended industrial temperature range (−40°C to +125°C).

Additional application and technical information can be found in the

ADA4099-2 data sheet.
