OP113/OP213/OP413 are low noise, low drift single-supply operational amplifiers that can operate with single or dual supplies. They feature low noise, wide bandwidth, low offset voltage, and very low drift. They are suitable for applications such as digital scales, multimedia, strain gages, battery-powered instrumentation, and temperature transducer amplifiers.
The OPx13 family (OP113, OP213, OP413) are single‑supply operational amplifiers designed for low noise (4.7 nV/√Hz) and low drift (0.2 µV/°C). They operate from 4 V to 36 V supplies and are suited for digital scales, multimedia, strain‑gage, battery‑powered instrumentation, and temperature‑transducer amplifiers.
The document includes detailed electrical characteristics, absolute maximum ratings, thermal resistance, ESD precautions, typical performance curves, and application circuits. Key specifications such as gain‑bandwidth product, slew rate, supply rejection ratio, and output swing are listed for each device variant.
