Single, Dual, Quad General Purpose Micropower,

RRIO 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.
