The ISL28288 is a dual channel micropower operational amplifier optimized for single supply operation over the 2.4V to 5.5V range. It can be operated from one lithium cell or two NiCd batteries. 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 to 100mV below the negative supply. The output operation is rail-to-rail. The ISL28288 draws minimal supply current while meeting excellent DC accuracy, AC performance, noise, and output drive specifications. The ISL28288 (10 Ld MSOP only) contains a power-down enable pin that reduces the power supply current to typically less than 4µA in the disabled state.
