ADA4084-2ARZ-RL

Overview

The Analog Devices ADA4084-2ARZ-RL is a dual-channel, single-supply operational amplifier featuring rail-to-rail input and output capabilities. It operates within a supply voltage range of +3 V to +30 V (±1.5 V to ±15 V). The device offers a gain bandwidth product of 15.9 MHz at AV = 100 and a typical unity-gain crossover frequency of 9.9 MHz. It maintains a low offset voltage of 100 µV maximum in the SOIC package and provides a high slew rate of 4.6 V/µs. Power consumption is low, with a typical supply current of 0.625 mA per amplifier at ±15 V.

Procurement Notes

Verify the specific ordering suffix ARZ-RL against the manufacturer's official documentation to confirm the package type and reel packaging configuration. Ensure compatibility with the required surface-mount footprint and check for any recent revision changes in the datasheet that may affect pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when designing circuits that require both high precision and wide bandwidth in a single-supply environment. The rail-to-rail capability allows for optimal use of the available supply voltage headroom. Consider the thermal resistance and package options if operating near the upper limits of the specified temperature range or under heavy load conditions.

Part Context

The ADA4084-2 is part of the ADA4084 family, which includes single (ADA4084-1), dual (ADA4084-2), and quad (ADA4084-4) variants. These amplifiers are designed for applications requiring high voltage operation up to 30 V with low noise characteristics. The series is suitable for portable telecommunications equipment and transducer interfaces where wide output ranges are necessary.
