Overview
The LT1716IS5#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 35µA. The unique input stage can withstand voltages up to 44V above the negative supply, independent of the positive supply voltage, and includes built-in resistors to protect the inputs from faults below the negative supply up to 5V. The LT1716 is available in a compact 5-lead SOT-23 package, making it suitable for space-constrained designs.
