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 are
a low supply current of 360µA maximum per channel
at room temperature, a low bias current and a wide
input voltage range, which enables 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.
