1716f

The LT

supply voltage between 2.7V and 44V drawing 35

µA of

quiescent current. The LT1716 has a unique input stage

(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 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.
