Dual Micropower Single Supply Rail-to-Rail Input And Output (RRIO) Precision Op Amp
The ISL28276 and ISL28476 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 EL8176.
These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages 10% above the positive supply rail and down to the negative supply. The output operation is rail to rail.
The ISL28276 and ISL28476 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28276 contains a power down enable pin that reduces the power supply current to typically 4A in the disabled state.
