AD8276BRMZ-RL

Instrumentation, Op Amps, Buffer Amps Overview

The AD8276BRMZ-RL is a single-channel, unity-gain difference amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of 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 (CMRR) of 86 dB at DC to 10 kHz. The device features a maximum system offset voltage of 200 µV and a maximum quiescent supply current of 200 µA per channel. It is housed in an 8-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific B-grade performance parameters against the official datasheet before integration. Confirm that the MSOP-8 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the application requirements. Validate that the supply voltage limits are not exceeded during operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a low-power, single-supply difference amplifier is required. It is optimized for applications needing high CMRR and wide input common-mode ranges. Consider the B-grade specifications for tighter offset and drift tolerances compared to other grades.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8276/AD8277 family of low-cost, low-power difference amplifiers. The AD8276 variant provides a single channel, whereas the AD8277 offers dual channels. Both share similar electrical characteristics and are designed for general-purpose precision signal conditioning.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-compatible replacements within the same series include the AD8276ARZ-RL (A-grade version) and the AD8276BRZ (tube packaging variant). Verify grade-specific parameter differences such as offset voltage and CMRR when substituting.
