Product Details

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).

Tools & Simulations


LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.


Models for the following parts are available in LTspice:


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.

Analog Photodiode Wizard

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.
