Level Shifting

The LT®1716 comparator operates on any total power
supply voltage between 2.7V and 44V drawing 35µA of

+

quiescent current. The LT1716 has a unique input stage
that can be taken 44V above V–, independent of V+ supply.
(Built-in resistors protect the inputs for faults below the
negative 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 pull­up 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.
