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.
