The ADA4099-1 and ADA4099-2 are single/dual robust, precision, rail-to-rail input/output operational amplifiers (op amps) with inputs that operate from −VS to +VS and beyond, which is referred to in this data sheet as Over-The-Top™. The devices feature offset voltages of <40 μV, input bias currents (IB) of <10 nA, and can operate on single or split supplies that range from 3.15 V to 50 V. The ADA4099-1 and ADA4099-2 draws 1.5 mA of quiescent current per channel.
The ADA4099-1 and ADA4099-2 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 input common-mode range extends from rail-to-rail and beyond, up to 70 V > –VS, independent of the +VS supply.
The ADA4099-1 and ADA4099-2 are 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 amplifiers are available with low power shutdown.
The ADA4099-1 is available in a standard, 6-lead, thin small outline transistor (TSOT) package. The ADA4099-2 is available in an 8- lead, standard small outline package (SOIC_N), 8-lead, mini small outline package (MSOP), and a 10-lead, lead frame chip scale package (LFCSP).

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
The EVAL-ADA4099-2EBZ evaluates the ADA4099-2 10-lead, lead frame chip scale package (LFCSP), robust Over-The-Top™ precision operational amplifier (op amp). The EVAL-ADA4099-2EBZ is a prepopulated board using a gain of 1 configuration.
The EVAL-ADA4099-2EBZ design allows simplified and efficient use. The EVAL-ADA4099-2EBZ 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-ADA4099-2EBZ ground plane, component placement, and power supply allow maximum circuit flexibility and performance. The EVAL-ADA4099-2EBZ uses a combination of surface-mount technology (SMT) with majority of components in 0603 case size, except for the 10 μF bypass capacitor. The EVAL-ADA4099-2EBZ also has unpopulated resistor and capacitor pads, which provide the user with the options and flexibility to implement different application circuits and configurations.
For full details on the ADA4099-2, see the ADA4099-2 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADA4099-2EBZ.
