Description
The ISL70218SRH is a 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. The ISL70218SRH features low power, low-offset voltage, and low-temperature drift, making it ideal for applications requiring both high DC accuracy and AC performance. The device 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 a small footprint provides the user with outstanding value and flexibility relative to similar competitive parts. Applications for this op amp include precision instrumentation, data acquisition, and precision power supply controls. The ISL70218SRH is available in a 10 Ld hermetic ceramic flatpack and operated across the extended temperature range of -55°C to +125°C.

ISL70218 Source and Sink Current
The sink and source current of 10mA is per amplifier. These amplifiers were designed to support a maximum output current of ±10mA for 20 years. Continuous operation greater than 10mA would violate our electromigration and lead to shortened product lifetime.
