AD824AR-14-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The AD824AR-14-REEL is a quad J-FET input operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output swing and operates from a single supply of 3 V to 30 V or dual supplies up to ±15 V. Key electrical parameters include a gain-bandwidth product of 2 MHz, a slew rate of 2 V/µs, an input bias current of 4 pA, and an input offset voltage of 500 µV. The device draws 560 µA for all four channels and provides 12 mA output current per channel. It is housed in a 14-SOIC package with an operating temperature range of -40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging when ordering. Confirm the '14' designation aligns with the 14-SOIC package variant. Ensure the manufacturer is Analog Devices Inc. Cross-reference the full part number against official distributor catalogs to distinguish between reel, cut tape, and tube packaging options before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring quad amplification with FET-input characteristics and rail-to-rail outputs. It is suitable for low-voltage environments where maximizing signal swing is critical. Consider the 2 MHz bandwidth and 2 V/µs slew rate for moderate-speed signal processing tasks. Verify that the 14-SOIC package fits the PCB layout constraints and thermal requirements of the design.
