The ISL71218M is a radiation tolerant dual, low-power precision amplifier optimized for single-supply applications. This op amp features a common-mode input voltage range extending to 0. 5V below the V- rail, a rail-to-rail differential input voltage range, and rail-to-rail output voltage swing, which makes it ideal for single-supply applications where input operation at ground is important. This op amp features low-power, Low-offset voltage, and low-temperature drift, making it ideal for applications requiring both high DC accuracy and AC performance. It is designed to operate over a single supply range of 3V to 36V, or a split supply voltage range of +1. 8V/-1. 2V to ±18V. The combination of precision and small footprint provides the user with outstanding value and flexibility relative to similar competitive parts. Applications for these amplifiers include precision instrumentation, data acquisition, and precision power supply controls. The ISL71218M is available in an 8 Ld SOIC and operates across the extended temperature range of -55°C to +125°C.
