Working Principles

The LM2901VQPWRG4 compares two input voltages and produces an output based on their relative magnitudes. It operates by amplifying the voltage difference between the inputs and comparing it to a reference voltage. If the voltage at the non-inverting input is higher than the voltage at the inverting input, the output goes high. Otherwise, the output goes low. This behavior makes it useful for various applications such as level shifting, signal conditioning, and threshold detection.
