The OP113/OP213/OP413 family are single‑supply operational amplifiers designed for low noise (4.7 nV/√Hz) and low offset drift (<0.8 mV/°C). They operate from 4 V to 36 V and are unity‑gain stable, making them suitable for digital scales, strain‑gage, battery‑powered instrumentation, and temperature‑transducer amplifiers. The devices support both single‑ and dual‑supply configurations and include built‑in phase‑reversal protection.
Key specifications include a gain‑bandwidth product of 3.4 MHz, slew rates up to 1.2 V/ms, output swing within 1 V of the supply rails, and PSRR of up to 100 dB. The datasheet also lists ordering options for various package types (SOIC, DIP, wide‑body) and provides typical performance curves for noise, gain, and output swing.
