GENERAL DESCRIPTION

The ADA4097-1 is a robust, precision, rail-to-rail input and output

operational amplifier (op amp) 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 offset voltages of <60 μV, input bias

currents (IB) of <0.3 nA, and can operate on single or split supplies

that range from 3 V to 50 V. The ADA4097-1 draws 32.5 μA of

supply current.

The ADA4097-1 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 common-mode input

range extends from rail-to-rail and beyond, up to 70 V > –VS,

independent of the +VS supply.

The ADA4097-1 is unity-gain stable and can drive loads requiring

up to 20 mA. The device can also drive capacitive loads as large as

200 pF. The amplifier is available with low power shutdown.

The ADA4097-1 is available in a standard, 6-lead, thin small

outline transistor (TSOT) package.
