Overview
The LT1716CS5#TRMPBF is a precision rail-to-rail comparator from Analog Devices Inc., designed for a wide range of applications requiring high accuracy and low power consumption. This comparator operates on any total power supply voltage between 2.7V and 44V, drawing a quiescent current of only 35µA. The LT1716 features a unique input stage that can withstand voltages up to 44V above the negative supply, independent of the positive supply voltage, making it highly versatile and robust. The device is available in a compact 5-lead TSOT-23 package, suitable for space-constrained designs.
