The LT1716IS5#TRMPBF is a micro-power Precision Rail-to-Rail Comparator operates on any total power supply voltage between 2.7 and 44V drawing 35μA of quiescent current. The LT1716 has unique input stage that can be taken 44V above V-, independent of V+ supply. The inputs can withstand 44V both differential and common mode. The output stage includes a class B pull-up current source, eliminating the need for an external resistive pull-up and saving power. Output voltage swings to within 35mV of the negative supply and 55mV of the positive supply, which makes the comparator a good choice for low voltage single supply operation. The output stage is also designed to drive loads connected to a higher supply than the LT1716 supply, the same as an open collector output stage.
