AD823AR

Instrumentation, Op Amps, Buffer Amps Overview

The AD823AR is a dual precision, 16 MHz JFET input operational amplifier manufactured by Analog Devices Inc. It operates from single supplies of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. The device features rail-to-rail output swing extending within 50 mV of the rails for low output currents. Key electrical parameters include a maximum input offset voltage of 800 µV, input bias current below 25 pA, and a supply current of 2.6 mA per amplifier. It provides a -3 dB bandwidth of 16 MHz, a slew rate of 22 V/µs, and drives up to 500 pF capacitive loads.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'AR' indicates the SOIC-8 surface-mount package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the operating temperature range aligns with industrial specifications (-40°C to +85°C). Cross-reference part numbers carefully to distinguish between tube and reel packaging options if applicable.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring high-speed signal processing with low power consumption. The JFET input stage offers high input impedance and low bias current, ideal for high-impedance sources. The rail-to-rail output maximizes signal swing in low-voltage single-supply systems. Consider the 16 MHz bandwidth and 22 V/µs slew rate for fast transient response requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD823AR belongs to the AD823 family of dual precision amplifiers. This series combines high AC performance with excellent DC accuracy. The 'AR' designation specifically identifies the plastic small-outline (SOIC) 8-lead package version. It serves as a versatile solution for applications needing both speed and precision in a compact form factor.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for AD823ARZ for lead-free compliant versions. Verify pinout compatibility with other dual JFET op-amps if substituting.
