AD8276ARMZ-R7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8276ARMZ-R7 is a single-channel unity-gain difference amplifier from Analog Devices, housed in an 8-lead MSOP package. It operates on supply voltages ranging from 2.0 V to 36 V (single) or ±2 V to ±18 V (dual). Key electrical specifications include a gain bandwidth product of 550 kHz, a slew rate of 1.1 V/µs, and a minimum common-mode rejection ratio of 86 dB. The device draws a maximum quiescent supply current of 200 µA per channel and features a system offset voltage of up to 500 µV for the A Grade.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel packaging configuration. Confirm the component grade corresponds to the necessary offset voltage and drift specifications for the target application environment. Ensure compatibility with the specified industrial temperature range during integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-power, wide-supply-range difference amplifier is required. It is optimized for precision signal conditioning where high common-mode rejection and extended input voltage ranges are critical. Consider the A Grade specifications if tighter offset voltage limits are necessary compared to the B Grade variant.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8276/AD8277 family of general-purpose unity-gain difference amplifiers. It is designed for power-critical applications requiring both high performance and low power dissipation. The device integrates internal resistors to provide a compact solution that outperforms discrete alternatives in size and cost.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8276ARZ-R7 serves as a direct alternative within the same series, differing primarily in the SOIC-8 package format instead of the MSOP-8 footprint. Both variants share identical electrical characteristics and pin configurations.
