Operational Amplifier

ISL28113, ISL28213, ISL28413

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 op-amps 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 over the extended temperature range of -40°C to

+125°C.
