Dual and Quad Micropower Single Supply Rail-to-Rail Input and Output (RRIO) Op-Amp

The ISL28288 and ISL28488 are dual and quad channel
micropower operational amplifiers optimized for single
supply operation over the 2.4V to 5V range. They can be
operated from one lithium cell or two Ni-Cd batteries. For
equivalent performance in a single channel op-amp
reference EL8188.
