AD8027ART-R2

Instrumentation, Op Amps, Buffer Amps Overview

The AD8027ART-R2 is a single-channel, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities within a 6-lead SOT-23 package. The device operates on supply voltages ranging from 2.7 V to 12 V with a typical quiescent current of 6.5 mA per amplifier. Key electrical specifications include a gain-bandwidth product of 190 MHz at unity gain, a slew rate of 100 V/µs, and an input voltage noise density of 4.3 nV/√Hz. It supports an extended operating temperature range from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the exact ordering suffix against official Analog Devices documentation to confirm packaging type and reel specifications. Ensure the component matches the required package variant (SOT-23) and that the DISABLE/SELECT pin configuration aligns with the intended circuit design for optimal performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier for applications requiring high bandwidth and low distortion in space-constrained designs. Consider the selectable crossover feature if optimizing for specific common-mode voltage ranges. Evaluate thermal dissipation requirements based on the SOT-23 package limitations and expected load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8027/AD8028 family of low distortion, high-speed amplifiers. The AD8027 is the single-channel version, while the AD8028 offers dual channels. Both utilize Analog Devices' extra fast complementary bipolar (XFCB) process technology to achieve high performance at low supply voltages.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify compatibility regarding package dimensions, pinout configurations, and electrical specifications before substitution.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the DISABLE/SELECT pin affect performance?

The DISABLE/SELECT pin controls the power-down mode and selects the input crossover threshold. Pulling it low disables the amplifier, while leaving it open or pulling it high shifts the crossover point between PNP and NPN input pairs to minimize distortion.

What is the input common-mode voltage range?

The inputs operate rail-to-rail, extending slightly beyond the supply rails. Specifically, the input stage can operate up to 200 mV beyond the positive supply rail without phase reversal.
