描述

The LTC8705/8706/8707/8708 devices are single-, dual-, and quad- channel comparators with open-drain output that are ideal for power-sensitive, low-voltage applications. Featuring a nano-power (typical 350 nA), fast 12 μs propagation delay, and a wide range of supply voltages from 1.7 V to 5.5 V with rail-to-rail common-mode voltage range makes the LTC8705/8706/8707/8708 an ideal choice for a wide variety of portable electronics applications, such as handsets, tablets, notebooks and portable devices that have extremely power constraints and tight board space.G5z先积集成-以创新缔造领先的中国模拟芯片

The output limits supply current surges and dynamic power consumption while switching.The open-drain output of the LTC8705/8706/8707/8708 can be used as a level-shifter using a pull-up resistor. It can also be used as a wired-OR logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals.G5z先积集成-以创新缔造领先的中国模拟芯片
