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).
- Industrial sensor conditioning
- Supply current sensing
- Battery and power supply monitoring

Evaluation Kits (1)
The EVAL-ADA4097-2EBZ evaluates the ADA4097-2 10-lead, lead frame chip scale package (LFCSP), robust Over-The-Top™ precision operational amplifier (op amp). The EVAL-ADA4097-2EBZ is a prepopulated board using a gain of 1 configuration.
The EVAL-ADA4097-2EBZ design allows simplified and efficient use. The EVAL-ADA4097-2EBZ has edge-mounted Subminiature Version A (SMA) connectors on the inputs and outputs to allow efficient connection to test equipment or other circuits. Bulk test points are also incorporated as an alternative option to be used for the inputs and outputs. The optimized EVAL-ADA4097-2EBZ ground plane, component placement, and power supply allow maximum circuit flexibility and performance. The EVAL-ADA4097-2EBZ uses a combination of surface-mount technology (SMT) with majority of components in 0603 case size, except for the 10 μF bypass capacitors (C1 and C4). The EVAL-ADA4097-2EBZ also has unpopulated resistor and capacitor pads that provide the user with options and flexibility to implement different application circuits and configurations.
Figure 1 in the user guide shows the primary side of the EVAL-ADA4097-2EBZ, and Figure 2 shows the secondary side of the EVAL-ADA4097-2EBZ.
Refer to the ADA4097-2 data sheet for full specifications, details on the device operation, and application circuit configurations. Consult the data sheet in conjunction with the user guide when using the EVAL-ADA4097-2EBZ.
