AD8028ARMZ-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8028ARMZ-REEL is a dual-channel, high-speed operational amplifier from Analog Devices featuring rail-to-rail input and output capabilities. It operates on supply voltages ranging from 2.7 V to 12 V. The device provides a typical gain-bandwidth product of 190 MHz at unity gain and a slew rate up to 100 V/µs. Input noise density is specified at 4.3 nV/√Hz with an input current noise of 1.6 pA/√Hz. Quiescent current consumption is typically 6.5 mA per amplifier. The component includes a power-down mode and selectable input crossover thresholds via the DISABLE/SELECT pin.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output stages enable full dynamic signal range operation on low supply voltages.
• Integrated DISABLE/SELECT pin allows users to configure input crossover points or activate a low-power shutdown mode.
• High-speed performance optimized for wide dynamic signal ranges with minimal phase reversal near supply rails.

Instrumentation, Op Amps, Buffer Amps Applications

• ADC drivers
• Professional video circuits
• Low voltage instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific suffix 'ARMZ-REEL' corresponds to the 8-lead SOIC package configuration as documented in the official ordering guide. Confirm that the manufacturing lot meets the required operating temperature range specifications before integration into final designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing systems requiring simultaneous high bandwidth and low distortion under single-supply conditions. Evaluate the trade-off between the 6.5 mA quiescent current and the 190 MHz bandwidth against alternative devices if strict power constraints exist.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8027/AD8028 family of amplifiers manufactured using Analog Devices' extra fast complementary bipolar (XFCB) process. While the AD8027 is a single-channel version, the AD8028 variant integrates two independent amplifiers within a single package to save board space.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8027ARMZ-REEL serves as a functional substitute if only one channel is required. Verify that the replacement maintains the same 8-lead SOIC footprint and electrical characteristics.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the DISABLE/SELECT pin affect the input stage?

The DISABLE/SELECT pin controls the crossover point between the PNP and NPN differential input pairs. Pulling it low activates power-down mode, while leaving it open or pulling it high selects different crossover locations to optimize precision for specific signal levels.

What is the maximum supply voltage for this device?

The absolute maximum supply voltage rating is 12.6 V, though the recommended operating range extends up to 12 V.
