GENERAL DESCRIPTION

The ADA4097-1/ADA4097-2 are single and dual robust, precision,

rail-to-rail input and output operational amplifiers (op amps) with

inputs that operate from −VS to +VS and beyond, which are referred

to in this data sheet as Over-The-Top™. The devices feature 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/ADA4097-2 draw 32.5 μA of supply current per

channel.

The ADA4097-1/ADA4097-2 Over-The-Top™ input stages have 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/ADA4097-2 are unity-gain stable and can drive

loads requiring up to 20 mA per channel. The devices can also

drive capacitive loads as large as 200 pF. The amplifiers are

available with low power shutdown.

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

transistor (TSOT) package. The ADA4097-2 is available in

an 8-lead standard small outline (SOIC_N) package, 8-lead mini

small outline package (MSOP), and 10-lead lead-frame chip-scale

package (LFCSP).
