Product Details

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).

Design Tool

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.
