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 of
low supply current of 130µA maximum per channel at
room temperature, low bias current and the wide input
voltage range enable 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, SO8 packages,
and the ISL28413 is in the TSSOP14, SOIC14 packages.
All devices operate over the extended temperature range
of -40°C to +125°C.
