... This results in low frequency noise performance which can only be found on devices with an order of magnitude higher supply current. ISL28168 and ISL28268 can be operated from one lithium cell or two Ni-Cd batteries. The ISL28168 contains an enable pin feature that allows the device to be shutdown when not in use ...

... Introduction The ISL28168 is a single CMOS rail-to-rail input, output (RRIO) operational amplifier with an enable feature. The ISL28268 is a dual version without the enable feature. Both devices are designed to operate from single supply (2.4V to 5.5V) or dual supplies (±1.2V to ±2.75V). Rail-to-Rail Input/Output Many rail-to-rail input stages use two differential input pairs, a long-tail PNP (or PFET) and an NPN (or NFET) ...

... Large (>2V) differential input voltages can also cause an increase in disabled I Using Only One Channel The ISL28268 is a dual op amp. If the application only requires one channel, the user must configure the unused channel to prevent it from oscillating. The unused channel will oscillate if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used ...
