AD8021ARMZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8021ARMZ-REEL7 is a single-channel voltage feedback operational amplifier manufactured by Analog Devices Inc. in an MSOP-8 package. It features a typical gain-bandwidth product of 1 GHz and a slew rate of 130 V/µs at ±5 V supply. The device operates within a supply range of ±2.25 V to ±12 V (4.5 V to 24 V total). Key electrical parameters include a maximum input offset voltage of 1 mV, 2.1 nV/√Hz input voltage noise, and 60 mA linear output current capability.

Instrumentation, Op Amps, Buffer Amps Feature Summary

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component matches the exact Analog Devices part number AD8021ARMZ-REEL7. Confirm the MSOP-8 package type and REEL7 tape-and-reel packaging format. Ensure the revision level corresponds to Rev F specifications. Check for RoHS compliance status as indicated in official documentation before integration into production designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier for applications requiring high speed combined with low noise characteristics. The custom compensation feature provides flexibility for gain settings between 1 and 10. Consider the output disable function for power-sensitive portable instrumentation designs. Verify that the required bandwidth and settling time meet the system specifications under the intended supply voltage conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8021 series of low-noise, high-speed amplifiers designed for 16-bit resolution systems. It is available in both SOIC-8 and MSOP-8 packages. The device is optimized for industrial temperature ranges and offers superior performance compared to standard high-speed op-amps with higher quiescent currents.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Do not assume functional equivalence with other high-speed amplifiers without reviewing specific electrical parameter comparisons.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the custom compensation feature benefit circuit design?

It allows the user to maximize bandwidth for closed-loop gains between 1 and 10 by adding an external capacitor, avoiding the fixed gain-bandwidth limitation of typical voltage feedback op-amps.

What is the purpose of the DISABLE pin?

The DISABLE pin reduces the quiescent supply current significantly when the output is disabled, which is useful for power management in portable instruments.
