ISL28278
feature an Input Range Enhancement Circuit (IREC) which enables both parts 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 100m V below the negative supply with only a slight degradation of the CMRR performance. The output operation is rail to rail. The both parts draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28278 and ISL28478 can be operated from one lithium cell or two Ni-Cd batteries. The input range includes .. both positive and negative rail.
