The ADA4084-2 (dual) and ADA4084-4 (quad) are single-supply, 10 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are guaranteed to operate from 3 V to 30 V (or ±1.5 V to ±15 V).
These amplifiers are well suited for single-supply applications requiring both ac and precision dc performance. The combina- tion of wide bandwidth, low noise, and precision makes the ADA4084-2 and ADA4084-4 useful in a wide variety of applications, including filters and instrumentation.
Other applications for these amplifiers include portable telecom- munications equipment, power supply control and protection, and use as amplifiers or buffers for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezoelectric, and resistive transducers.
The ability to swing rail-to-rail at both the input and output enables designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios.
The ADA4084-2 and ADA4084-4 are specified over the industrial temperature range of −40°C to +125°C. The dual ADA4084-2 is available in the 8-lead SOIC, MSOP, and LFCSP surface-mount packages, and the ADA4084-4 is offered in the 14-lead TSSOP and 16-lead LFCSP.

OpAmp Error Budget Calculator
An online tool to illustrate range, gain and accuracy issues in simple opamp buffers.
|Amplifier Error Budget Analysis||HTML|
This tool will help with the selection, evaluation and troubleshooting of voltage feedback Op-Amps. It uses typical data to model the behavior of a selected amplifier. It allows a user to select an amplifier, configure a circuit, apply a signal and evaluate the performance. It is useful for checking an amplifier's spec's such as Bandwidth, Slew Rate, Input/Output Range, Gain Error, Load Current, Stability Issues and DC Errors in a given circuit.
