```Linear – ComparatorsLM2903WYDT is a general purpose, high-performance dual comparator from National Semiconductor Corporation. This device uses advanced CMOS technology to provide reliable, low-power low-offset comparator performance. It has two independent comparators in one package. These comparators provide open-collector output capable of sourcing and sinking up to 30mA with the capability to operate from a single power supply that is in the range of 2V to 36V. The LM2903WYDT is designed to detect logic changes in input voltage that is often required in a wide range of applications, such as temperature sensing and optical sensing.This device offers Rail-to-Rail input voltage levels with thresholds guaranteed to be within 100mV of the supply voltage with an hysteresis of 25mV. The output of these comparators is capable of sampling speeds up to 500KHz and can handle low-level input signals. The LM2903WYDT is stable when used in the most demanding conditions such as high-voltage, high-temperature, or high-impedance.Applications:LM2903WYDT is a versatile device that is suitable for many applications. It can be used in photodiode and thermistor sensors, wireless remote control systems, in switches, level detectors, high-impedance circuit monitoring, micropower voltage detectors, for logic level shifting, etc.Working Principle:The LM2903WYDT comparator compares two independent adjustable differential input voltages and provides an output logic depending upon their magnitude. It has two separate non-inverting inputs and one inverting input that is shared between the two comparators. This device also has two status flags, both active low that are asserted when the appropriate input reaches its threshold.When the non-inverting input voltage is greater than the inverting input voltage, the output will go low and the “SL” (status low) flag will be asserted. This indicates that the comparator output is in the low state. When the non-inverting input voltage is lower than the inverting input voltage, the output will go high and the “SH” (status high) flag will be asserted. This indicates that the comparator output is in the high state.The LM2903WYDT has low input bias and offset currents, low power consumption, and low output saturation voltages. It also has good linearity, minimal power supply noise coupling, and fast response time making it an ideal choice for many applications.In conclusion, the LM2903WYDT is a versatile, high performance dual comparator from National Semiconductor Corporation. It has two independent comparators in one package and provides reliable performance in a wide range of applications. The device has Rail-to-Rail input voltage levels with guaranteed thresholds, low power consumption, low saturation voltage, and fast response times making it an ideal choice for many applications.
