The ISL28113, ISL28213 and ISL28413 are single, dual and quad channel general purpose micropower, rail-to-rail input and output operational amplifiers with supply voltage range of 1. 8V to 5. 5V. Key features are a low supply current of 130µA maximum per channel at room temperature, a low bias current and a wide input voltage range, which enables the ISL28x13 devices to be excellent general purpose operational amplifiers for a wide range of applications. The ISL28113 is available in the SC70-5 and SOT23-5 packages, the ISL28213 is in the MSOP8, SOIC8, SOT23-8 packages and the ISL28413 is in the TSSOP14, SOIC14 packages. All devices operate across the extended temperature range of -40°C to +125°C.
