The LTC1443IN#PBF manufactured by Analog Devices is a low-power, quad-comparator device with 1% accuracy and a 1.182V reference voltage. It features high-precision analog comparator architecture with a fast response time, low input bias current, hysteresis, and high rail-to-rail input and output capabilities. The quad comparator helps with voltage monitoring, overvoltage/undervoltage protection, motor control, current monitoring, pulse width modulation (PWM) control, level sensing, etc. It offers good noise immunity for noise-sensitive circuits and is designed to operate at very low supply voltage levels, typically down to 1.65V. It is offered in a space-saving 8-pin PDIP or 8-pin MSOP package and is rated for operation from -40°C to 85°C.
