AD822AR-REEL7

The Analog Devices AD822AR AD822AR Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 7852 -REEL7 is a dual operational amplifier designed for general-purpose signal conditioning in systems requiring low power consumption and rail-to-rail output swing. This 2-circuit amplifier operates across a wide supply voltage range from 5V to 30V, making it suitable for both single-supply and split-supply configurations commonly encountered in battery-powered instrumentation, portable test equipment, and mixed-signal data acquisition systems.

With a gain bandwidth product of 1.9 MHz and a slew rate of 3V/µs, the AD822AR AD822AR Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 7852 -REEL7 provides adequate bandwidth for audio processing, sensor signal amplification, and low-frequency filtering applications where precision rather than high-speed performance is the primary design requirement. The rail-to-rail output capability allows the amplifier to drive signals close to the supply rails, maximizing dynamic range in single-supply designs and reducing the need for level-shifting circuitry in interface applications.

Input bias current of 2 pA and input offset voltage of 400 µV enable operation in high-impedance source conditions such as photodiode preamplification and piezoelectric sensor interfacing. The low input bias current reduces errors when working with resistances in the megohm range, while the moderate offset voltage remains manageable through standard offset compensation techniques. Supply current of 1.24 mA per amplifier supports battery-operated applications where power budget constraints influence component selection.

Each amplifier channel delivers up to 20 mA output current, sufficient to drive moderate capacitive loads or multiple high-impedance inputs without external buffering. The device functions reliably across the industrial temperature range of -40°C to 85°C, addressing requirements in automotive sensor interfaces, industrial process control loops, and outdoor monitoring systems where ambient temperature varies significantly.

Housed in an 8-SOIC surface mount package with 3.90mm body width, the AD822AR AD822AR Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 7852 -REEL7 occupies minimal board space while maintaining compatibility with standard reflow soldering processes. The component carries MSL-1 moisture sensitivity classification, eliminating floor life restrictions and simplifying inventory management in production environments. Though currently classified as obsolete by the manufacturer, existing stock remains available for legacy system maintenance, production sustaining activities, and designs where form-fit-function equivalency must be preserved. Alternative devices such as the AD822ARZ-REEL7 AD822ARZ-REEL7 Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 15400 , LT1638IS8#TR LT1638IS8#TR Analog Devices Inc.

What the Analog Devices AD822AR-REEL7 Provides in the Original Circuit

AD822AR AD822AR Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 7852 -REEL7 is a dual general-purpose amplifier with rail-to-rail output capability in an 8-SOIC surface-mount package. Its two-amplifier configuration, standard SOIC footprint, and broad supply range make it suitable for many legacy analog signal-conditioning boards.

The AD822AR AD822AR Analog Devices Inc. IC OPAMP GP 2 CIRCUIT 8SOIC 7852 -REEL7 is commonly used in analog buffers, active filters, sensor signal conditioning, low-bias-current measurement paths, battery-powered instruments, data acquisition interfaces, and general-purpose voltage amplification. Its 2 pA input bias current is especially relevant in high-source-impedance circuits, while the 3 V/µs slew rate and 1.9 MHz bandwidth support moderate-speed analog signals.

Replacement decisions should focus on how the amplifier is used. If the circuit is a low-frequency precision sensor interface, input bias current and offset voltage may dominate. If it is an active filter or ADC input buffer, bandwidth, slew rate, phase margin, output swing, and capacitive-load behavior require attention. If the PCB cannot change, SOIC-8 mechanical compatibility and pinout alignment become major selection filters.
