概览

The ISL28248 is a 4.5MHz low-power dual operational amplifier. The part is optimized for single supply operation from 2.4V to 5.5V, allowing operation from one lithium cell or two NiCd batteries. The device features an Input Range Enhancement Circuit (IREC), which enables it 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. Operation is guaranteed across the -40 °C to +125 °C temperature range.
