AD8676BRMZ

Overview

The AD8676BRMZ is a dual precision operational amplifier from Analog Devices, housed in an 8-lead Mini Small Outline Package (MSOP). It features ultralow offset voltage of 12 μV typical and low input bias current of 2 nA maximum. The device offers a wide bandwidth with a gain-bandwidth product of 10 MHz and a slew rate of 2.5 V/μs. It operates on supply voltages ranging from ±5 V to ±18 V, providing rail-to-rail output swing. Key electrical specifications include a common-mode rejection ratio of 130 dB and a power supply rejection ratio of 120 dB.

Feature Summary

• Combines ultralow offset voltage and drift with very low input bias currents for high DC precision.
• Features rail-to-rail output swing capability alongside wide bandwidth and low noise performance.
• Designed for extended industrial temperature operation without shutdown functionality.

Applications

• Precision instrumentation
• PLL filters
• Laser diode control loops
• Strain gage amplifiers
• Medical instrumentation

Procurement Notes

Verify the specific grade B designation associated with the BRMZ suffix against the manufacturer's ordering guide to confirm offset voltage limits. Ensure the MSOP package option matches the required PCB footprint dimensions. Confirm RoHS compliance status as indicated by the Z suffix in the official documentation before finalizing procurement orders.

Selection Notes

Select this component when applications require simultaneous low noise, wide bandwidth, and high DC accuracy. The dual configuration allows for space-critical designs requiring two channels in a compact package. Consider the rail-to-rail output feature if maximizing dynamic range is necessary within the specified supply voltage constraints.

Part Context

This part belongs to the AD8676 series of ultraprecision, rail-to-rail output operational amplifiers manufactured by Analog Devices. The series includes single-channel (AD8675) and quad-channel (AD8674) variants. The BRMZ variant specifically denotes the Grade B performance level packaged in the lead-free 8-lead MSOP format.

Replacement Considerations

The AD8676ARMZ serves as a functional substitute within the same family, offering identical electrical characteristics but packaged in the standard SOIC format rather than the MSOP.
