The LT^®1716 comparator operates on any total powersupply voltage between 2.7V and 44V drawing 35µA ofquiescent current. The LT1716 has a unique input stagethat can be taken 44V above , independent of V+ supply.(Built-in resistors protect the inputs for faults below thenegative supply of up to 5V.) 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.

The LT1716 is available in a SOT-23 5-lead package.
