The OP193 family is a single-supply operational amplifier with high precision, low supply current, and the ability to operate at low voltages. It is suitable for applications such as digital scales, strain gages, portable medical equipment, battery-powered instrumentation, and temperature transducer amplifiers.
This document describes the OP193 family of single-supply operational amplifiers, which combine high precision with low supply current capabilities. These devices are designed for battery-powered instrumentation and operate from +1.7 V to +18 V, with input and output ranges that include ground for single-supply systems. The family is specified for operation over a temperature range of -40°C to +125°C and is available in plastic DIP and SOIC surface mount packages.
The datasheet provides detailed electrical specifications for the OP193, OP293, and OP493 variants under various supply voltage conditions (from +2.0 V to +18 V). Key parameters include offset voltage, input bias current, large signal voltage gain, power supply rejection ratio, noise performance, and dynamic characteristics such as slew rate and gain bandwidth product.
