DATASHEET
ISL28114, ISL28214, ISL28414
Single, Dual, Quad General Purpose Micropower, RRIO Operational Amplifiers
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 390µA
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, and SOT23-8
packages, and the ISL28414 is in the TSSOP14 and SOIC14
packages. All devices operate across the extended
temperature range of -40°C to +125°C.
