The ISL28288 is a dual channel micropower precision operational amplifier optimized for single supply operation at 5V and can operate down to 2.4V. For equivalent performance in a single channel op-amp reference EL8188. The ISL28288 features an Input Range Enhancement Circuit (IREC) which enables the ISL28288 to maintain CMRR performance for input voltages equal to the positive and negative supply rails. The input signal is capable of swinging 10% above the positive supply rail and to 100mV below the negative supply with only a slight degradation of the CMRR performance. 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.
