ISL28138FHZ-T7A General Description

Support is limited to customers who have already adopted these products.

The ISL28138 and ISL28238 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 parts 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 ISL28138 features an enable pin that can be used to turn the device off and reduce the supply current to less than 20µA. Operation is guaranteed over -40°C to +125°C temperature range.
