Intersil ISL28113, ISL28213, ISL28413 User Manual

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.
