OP481GRU-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The OP481GRU-REEL is a quad operational amplifier manufactured by Analog Devices Inc., featuring rail-to-rail output capabilities. It operates within a supply voltage range of 2.7 V to 12 V, with a maximum dual supply of 6 V. Key electrical parameters include a gain-bandwidth product of 105 kHz, a slew rate of 27 mV/us, and an input offset voltage of 1.5 mV. The device draws 16 uA of operating current per channel and exhibits an input bias current of 10 nA. It is housed in a 14-TSSOP package and functions reliably across a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix GRU against official Analog Devices documentation to confirm the 14-TSSOP package variant. Ensure the REEL packaging designation matches your automated assembly requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with rail-to-rail output is required under single-supply conditions. Compare its 105 kHz bandwidth and 16 uA quiescent current against other general-purpose op-amps. Consider the 1.5 mV input offset voltage for precision requirements. Verify that the 14-TSSOP footprint fits your PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OP481 series of quad operational amplifiers from Analog Devices. It complements other members of the family such as the OP481GSZ and OP481ARUZ, differing primarily in package type and reel packaging specifications. The series is designed for general-purpose analog signal conditioning tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible substitutes like the OP481GSZ or OP481ARUZ if package availability differs. Verify that alternative quad op-amps meet the same rail-to-rail output and low-power specifications.
