Its 2 µV typical input offset voltage and 20 pA input bias current make it a natural fit for precision DC signal conditioning — think thermocouple amplifiers, strain-gauge bridges, or photodiode transimpedance stages where offset drift over temperature would otherwise dominate the error budget. The 125 kHz gain-bandwidth product and 0.06 V/µs slew rate define the usable signal bandwidth. For a closed-loop gain of 100, the -3 dB bandwidth is roughly 1.25 kHz — adequate for low-frequency sensor outputs but not for audio or fast servo loops. The 13 µA supply current per channel (26 µA total for both amplifiers) keeps the power budget light in battery-operated or loop-powered designs. ## Supply range and output swing Output drive capability is 15 mA per channel — enough to drive a successive-approximation ADC input or a reference buffer without an additional gain stage.","metaTitle":"ADA4051-2ARMZ-R7 Zero-Drift Op-Amp, 125 kHz, 2 µV Offset","metaDescription":"Analog Devices ADA4051-2ARMZ-R7 dual zero-drift op-amp, 125 kHz GBW, 2 µV offset, 13 µA supply.

The pinouts differ — the dual-channel part has two amplifier inputs and outputs on the same footprint. A board laid out for the single-channel ADA4522 would need a layout change to accommodate the second channel. Parametrically, the ADA4522 offers higher bandwidth (2.7 MHz) and higher supply current (800 µA per channel), so a direct substitution without evaluating the system-level trade-offs is not recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADA4051-2ARMZ-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADA4051-2ARMZ-R7 when reusing this data.
