Zero-drift precision operational amplifier provides rail-to-rail output swing for high-accuracy low-frequency signal conditioning. The amplifier operates from a 4.5 V to 30 V single supply or ±2.25 V to ±15 V dual supplies while drawing less than 0.95 mA at ±5 V. It specifies 4 μV maximum offset voltage, 0.05 μV/°C maximum offset drift, and 1.2 μV p-p noise from 0.1 Hz to 10 Hz. The device is specified across the extended industrial −40°C to +125°C temperature range and is offered in 8-lead LFCSP and SOIC package options.
