LT1716 - SOT-23, 44V, Over-The-Top, Micropower, …

1 LT1716 . SOT-23, 44V, Over-the-Top, Micropower, precision rail -to- rail Comparator FEATURES DESCRIPTION. n Operates from to 44V The LT 1716 comparator operates on any total power n Over-The-Top : Input Common Mode Range supply voltage between and 44V drawing 35 A of Extends 44V Above V , Independent of V+ quiescent current. The LT1716 has a unique input stage n Micropower: 35 A IQ that can be taken 44V above V , independent of V+ supply. n Offset Voltage: Max (Built-in resistors protect the inputs for faults below the n Valid Output with Either Input 5V Below V negative supply of up to 5V.) The inputs can withstand n rail -to- rail Output Swing 44V both differential and common mode.

2 N Output Can Drive Loads Above V+. n The output stage includes a class B pull-up current Internal Pull-Up Current n source, eliminating the need for an external resistive 40 C to 125 C Operating Temperature Range n pull-up and saving power. Output voltage swings to within Low Pro le (1mm) SOT-23 (ThinSOT ) Package 35mV of the negative supply and 55mV of the positive supply, which makes the comparator a good choice for APPLICATIONS low voltage single supply operation. The output stage is n also designed to drive loads connected to a higher supply Power Supply Monitors n than the LT1716 supply, the same as an open collector Relay/Lamp Driver n output stage.
