AD8226BRMZ-R7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8226BRMZ-R7 is a precision instrumentation amplifier manufactured by Analog Devices Inc. It features a wide supply range of 2.2 V to 36 V single-supply or ±1.35 V to ±18 V dual-supply, and rail-to-rail output capability. Gain is set via one external resistor with a range of 1 to 1000. Key electrical parameters include a 1.5 MHz bandwidth at G=1, 90 dB minimum CMRR at G=1 for BR models, 22 nV/√Hz input noise, and 350 μA typical quiescent current. The device operates from −40°C to +125°C in an 8-lead MSOP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the BRMZ designation corresponds to the higher CMRR specification compared to ARMZ variants. Ensure the component matches the required temperature grade and package dimensions for the target PCB layout before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this part for applications requiring high common-mode rejection and wide supply flexibility. The BR variant offers superior CMRR compared to the AR series. Consider the MSOP package for space-constrained designs. Verify that the gain-setting resistor tolerance meets system accuracy requirements as it directly impacts overall gain error.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the AD8226 family of low-cost, wide supply range instrumentation amplifiers. It shares architectural similarities with other devices in the Analog Devices portfolio but is distinguished by its specific combination of rail-to-rail output and wide input overvoltage protection capabilities within the MSOP form factor.
