Single, Dual, Quad General Purpose Micropower,
RRIO Operational Amplifiers
ISL28114, ISL28214, ISL28414
The ISL28114, ISL28214, and ISL28414 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 360µA maximum per channel at
room temperature, low bias current and the wide input
voltage range enable the ISL28x14 devices to be
excellent general purpose op-amps for a wide range of
applications.
The ISL28114 is available in the SC70-5 and SOT23-5
packages, the ISL28214 is in the MSOP8, SO8
packages, and the ISL28414 is in the TSSOP14,
SOIC14 packages. All devices operate over the
extended temperature range of -40°C to +125°C.
