It runs on a single supply from 2.4 V to 5.5 V, drawing 420 µA per channel — a fit for battery-powered or low-power rail designs where every milliamp counts. The rail-to-rail output stage swings close to the supply rails, preserving dynamic range in low-voltage signal chains. Input bias current sits at 0.1 pA, which keeps offset errors negligible when the source impedance is high — think photodiode transimpedance or pH probe buffers. Offset voltage is trimmed to 70 µV, so you can skip the nulling pot in most precision DC-coupled stages. The -40°C to 85°C industrial temperature grade covers outdoor telecom cabinets, factory-floor sensor interfaces, and automotive-cabin modules. ## Package and mounting — 8-SOIC, tube delivery, surface-mount reflow The part comes in an 8-SOIC package (0.154-inch body width, 3.90 mm), supplied in a tube. It is a surface-mount device intended for standard reflow soldering.","metaTitle":"MAX4257ESA+ Dual Rail-to-Rail Op-Amp, 22 MHz GBW, 8-SOIC","metaDescription":"Maxim MAX4257ESA+ dual general-purpose op-amp. 22 MHz GBW, 2.1 V/µs slew rate, 70 µV offset, rail-to-rail output. 8-SOIC, -40°C to 85°C.
