AD8276BRMZ-R7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8276BRMZ-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 bandwidth of 550 kHz, a slew rate of 1.1 V/µs, and a minimum common-mode rejection ratio of 86 dB. The device features a maximum quiescent supply current of 200 µA per channel and a system offset voltage of 200 µV for the B Grade.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix R7 corresponds to the reel packaging configuration required for your assembly process. Confirm that the B Grade performance parameters meet your design requirements regarding offset voltage and CMRR limits. Ensure the MSOP-8 footprint matches your PCB layout constraints and thermal management strategy.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing power-critical applications requiring both high performance and low power consumption. It is suitable for single-supply systems needing a high common-mode voltage range. Consider the B Grade specifications if tighter tolerance on offset voltage and drift is necessary compared to lower grades.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8276/AD8277 family of low power, wide supply range, low cost unity-gain difference amplifiers. The AD8276 variant provides a single channel, whereas the AD8277 offers dual channels. Both are designed for precision signal conditioning in industrial and portable applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8276BRZ is a pin-compatible alternative available in an SOIC-8 package. Designers should verify package dimensions and thermal characteristics when substituting between MSOP and SOIC formats.
