概要
説明
The ISL28118, ISL28218 are single and dual, low-power precision amplifiers optimized for single-supply applications. These devices feature a common mode input voltage range extending to 0. 5V below the V- rail, a rail-to-rail differential input voltage range for use as a comparator and rail-to-rail output voltage swing, which makes them ideal for single-supply applications where input operation at ground is important. These op amps feature low power, low offset voltage and low temperature drift, making them the ideal choice for applications requiring both high DC accuracy and AC performance. These amplifiers are designed to operate over a single supply range of 3V to 40V or a split supply voltage range of +1. 8V/-1. 2V to ±20V. 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, precision power supply controls and industrial controls. Both parts are offered in 8 Ld SOIC and 8 Ld MSOP packages. All devices are offered in standard pin configurations and operate across the extended temperature range of -40°C to +125°C.
