Nano Power, Push/Pull Output Comparator
ISL28915
Features
The ISL28915 is a nano power comparator optimized for
low-power applications. This device is designed for
single-supply operation from 1.8V to 5.5V and typically
consumes 500nA of supply current. These devices also feature
a push/pull output stage with rail-to-rail input and output
swing (RRIO), allowing for maximum battery usage.
