® Data Sheet ISL28278, ISL28478 September 28, 2006 FN6145.1 Dual Micropower Single Supply Rail-to-Rail Input and Output (RRIO) Precision Op-Amp The ISL28278 and ISL28478 are Dual and Quad 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 EL8178. The ISL28278 and ISL28478 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 100mV 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. Ordering Information PART TAPE & PKG.
