AD627BRZ-RL

Instrumentation, Op Amps, Buffer Amps Overview

The AD627BRZ-RL is a low-power instrumentation amplifier from Analog Devices, featuring rail-to-rail output and single-supply operation. It operates on voltages from +2.2 V to ±18 V with a maximum supply current of 85 μA. The device offers a gain range of 5 to 1000 via a single external resistor. Key electrical specifications include an input offset voltage of 25 μV (typical), a common-mode rejection ratio of 83 dB, and a bandwidth of 80 kHz at unity gain. It utilizes an SOIC-8 package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the BRZ variant meets required temperature and accuracy grades. Check current availability status as distribution may be limited. Ensure compatibility with existing PCB footprints for SOIC-8 packages during integration planning.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low quiescent current and precise DC performance. The rail-to-rail output allows operation near supply rails, maximizing headroom in single-supply designs. Consider the 80 kHz bandwidth limit for high-speed signal requirements. Evaluate the 83 dB CMRR against system noise floors to ensure adequate interference rejection.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD627 family of micro-power instrumentation amplifiers. It shares core architecture with other variants like the AD627AR but differs in precision grades and packaging. The BRZ designation typically denotes a specific temperature range and lead-free compliance within the standard industrial product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include other AD627 variants such as AD627AR or AD627BRZ depending on packaging needs. Cross-reference pinouts and electrical specs carefully. Verify that alternative devices maintain similar power consumption and gain settings.
