AD8091ART-R2

Instrumentation, Op Amps, Buffer Amps Overview

The AD8091ART-R2 is a low-cost, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features true single-supply operation with an input voltage range extending 200 mV below the negative rail and within 1 V of the positive rail. The output swings to within 25 mV of either supply rail, providing maximum dynamic range. Key electrical specifications include a small-signal bandwidth of 110 MHz at unity gain (G = +1), a slew rate of 145 V/μs, and a settling time of 50 ns to 0.1%. It operates on supply voltages ranging from 3 V to 12 V with a quiescent current of approximately 4.4 mA per amplifier.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix ART-R2 corresponds to the SOT-23-5 package variant as specified in the manufacturer's documentation. Confirm the revision level matches the required datasheet version. Ensure the component meets the operating temperature range requirements for the intended environment. Cross-reference the part number with official distributor catalogs to validate authenticity and availability status before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier when high-speed signal processing is required alongside low power constraints. It is suitable for designs needing rail-to-rail output swing without dual supplies. Consider its noise characteristics and distortion levels for video or precision applications. Evaluate thermal dissipation capabilities if operating near maximum ambient temperatures or under heavy load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8091/AD8092 family of low-cost, high-speed rail-to-rail amplifiers. The AD8091 represents the single-channel configuration, while the AD8092 is the dual-channel version. Both share similar electrical characteristics but differ in pin count and package options, offering flexibility for various circuit board layouts and channel density requirements.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct substitutes within the same product family, such as the AD8092 for dual-channel needs. Verify compatibility with existing PCB footprints, specifically the SOT-23-5 package dimensions. Ensure replacement parts maintain equivalent bandwidth, slew rate, and power supply voltage ranges.
