OP291GS-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The OP291GS-REEL7 is a dual-channel, general-purpose operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, allowing operation with single supplies ranging from 2.7 V to 12 V or dual supplies up to ±6 V. The device draws a supply current of 800 µA per channel and offers a gain-bandwidth product of 3 MHz with a slew rate of 400 mV/µs. Input offset voltage is specified at 700 µV, with an input bias current of 65 nA. It operates within a temperature range of -40°C to +125°C and is housed in an 8-SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix REEL7 confirms tape and reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical specifications. Check for RoHS compliance status if required by project standards. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when dual-channel performance with rail-to-rail I/O is required under single-supply conditions. Compare against the OP291GS variant to confirm packaging differences. Evaluate the 800 µA supply current against stricter low-power alternatives if battery life is critical. Verify that the 3 MHz bandwidth meets the signal frequency requirements of the application.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OP291 family of micro-power, rail-to-rail operational amplifiers. It shares architectural similarities with the OP191 (single channel) and OP491 (quad channel). The GS suffix indicates the SOIC-8 package option. The REEL7 designation specifies the reel quantity and packaging format for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The OP291GS is listed as obsolete in some distributor records. Verify availability of the OP291GSZ-REEL7 as a potential active replacement. Ensure pin compatibility and electrical parameters match before substituting.
