The ISL28236 is a low-power dual operational amplifier optimized for single supply operation from 2.4V to 5.5V, allowing operation from one lithium cell or two Ni-Cd batteries. The device features a gain-bandwidth product of 5MHz. The ISL28236 features an Input Range Enhancement Circuit (IREC), which enables the amplifier 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 the negative supply with only a slight degradation of the CMRR performance. The output operation is rail-to-rail. The part typically draws less than 1mA supply current per amplifier while meeting excellent DC accuracy, AC performance, noise and output drive specifications. The ISL28236 is available in the 8 Ld SOIC and the 8 Ld MSOP. Operation is guaranteed over the -40 °C to +125 °C temperature range.
