Overview

The ISL28148, ISL28248 are 4. 5MHz low-power single and dual operational amplifiers. The parts are optimized for single supply operation from 2. 4V to 5. 5V, allowing operation from one lithium cell or two Ni-Cd batteries. The single and dual feature an Input Range Enhancement Circuit (IREC), which enables them to maintain CMRR performance for input voltages greater than the positive supply. The input signal is capable of swinging 0. 25V above the positive supply and to 100mV below the negative supply with only a slight degradation of the CMRR performance. The output operation is rail-to-rail. The parts draw minimal supply current (900μA per amplifier) while meeting excellent DC accuracy, AC performance, noise and output drive specifications. The ISL28148 features an enable pin that can be used to turn the device off and reduce the supply current to a maximum of 16μA. Operation is guaranteed across the -40°C to +125°C temperature range.
