ANALOG DEVICES LT1716CS5#TRMPBF Analogue Comparator, Micropower, Precision, 1 Channels, 5.5 µs, 2.4V to 2.7V, TSOT-23, 5 Pins

LT1716 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 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. Applications include power supply monitors, relay/lamp driver, oscillators, peak detector and level shifting.
