Supply range spans 5 V to 36 V, making it equally at home on a single 5 V rail or a ±15 V split supply. The rail-to-rail output swings close to both supply rails, maximizing dynamic range in low-voltage systems. The 8-SOIC package is surface-mount, so it reflows on a standard profile and fits a compact PCB layout.","metaTitle":"AD820AR-3V JFET Op-Amp, 1.9 MHz, Rail-to-Rail Output, 8-SOIC","metaDescription":"ADI AD820AR-3V single JFET op-amp: 1.9 MHz GBW, 3 V/µs slew rate, rail-to-rail output, 700 µA supply, -40°C to 85°C.

If you need a higher-speed JFET op-amp, the AD8627 (5 MHz, 5 V/µs) is a pin-compatible alternative in 8-SOIC."},{"question":"What is AD820AR-3V's listed slew rate?","answer":"The slew rate is 3 V/µs, typical for a 1.9 MHz JFET op-amp. That means it can reproduce a 1 V peak-to-peak sine wave cleanly up to about 480 kHz — fine for audio, sensor filtering, and control loops."},{"question":"Is AD820AR-3V a rail-to-rail output op amp?","answer":"Yes, the output stage is rail-to-rail, meaning it can swing within millivolts of both supply rails. This is useful in single-supply designs (e.g., 5 V only) where you need the full voltage range into an ADC or comparator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD820AR-3V","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD820AR-3V when reusing this data.
