It delivers a 1 MHz gain-bandwidth product and a 1.4 V/µs slew rate. The rail-to-rail output swings close to the supply rails. Supply span runs from 2 V up to 36 V. Input offset voltage is trimmed to 50 µV typical, keeping the DC error low enough for precision current-sense and bridge-amplifier circuits without an external null pot. The 200 µA supply current is a key number for multi-channel boards where every milliamp adds up — you can run several of these off a single low-dropout regulator without thermal headaches. Temperature grade is -40°C to 85°C, which covers industrial enclosures, outdoor telecom cabinets, and under-hood automotive cabin environments (though not AEC-Q100 qualified per the listing). The 8-SOIC package is a standard footprint; the tube delivery works for prototype runs and small-batch production where you don't want to commit to a full reel. ## Where it fits — typical application scenarios The differential topology suits high-side current sensing, where the amplifier must reject the common-mode voltage swing. The rail-to-rail output and wide supply range interface directly with ADCs without an extra level-shifter stage.","metaTitle":"AD8278ARZ Differential Op-Amp, 1 MHz GBW","metaDescription":"AD8278ARZ differential amplifier from Analog Devices. 1 MHz GBW, 1.4 V/µs slew rate, rail-to-rail output, 2-36 V supply.

This allows the signal to swing within millivolts of the supply rails, maximizing dynamic range when driving an ADC input from a low-voltage supply."},{"question":"What is the equivalent of AD8278ARZ?","answer":"The closest functional equivalent is the AD8278ARMZ-R7, which uses the same die in a tape-and-reel package. The AD8276BRZ-R7 is a lower-bandwidth sibling (550 kHz, 1.1 V/µs) with otherwise identical pinout and supply range. Neither is a second-source — both are ADI parts — but either can serve as a drop-in for prototype or production flexibility."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/AD8278ARZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/AD8278ARZ when reusing this data.
