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.
