LT1716 SOT-23, 44V, Over-the-Top, Micropower, Precision Rail-to-Rail Comparator FEATURES DESCRIPTION n Operates from 2.7V to 44V The LT 1716 comparator operates on any total power n Over-The-Top : Input Common Mode Range supply voltage between 2.7V and 44V drawing 35A of + Extends 44V Above V , Independent of V quiescent current. The LT1716 has a unique input stage + n Micropower: 35A I that can be taken 44V above V , independent of V supply. Q n Offset Voltage: 1.5mV 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. + n Output Can Drive Loads Above V The output stage includes a class B pull-up current n Internal Pull-Up Current source, eliminating the need for an external resistive n 40C to 125C Operating Temperature Range pull-up and saving power. Output voltage swings to within n 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 also designed to drive loads connected to a higher supply n Power Supply Monitors than the LT1716 supply, the same as an open collector n Relay/Lamp Driver output stage. n Oscillators n The LT1716 is available in a SOT-23 5-lead package.
