Working Principles

The LMV393IPWRG4 operates based on the principle of voltage comparison. It compares the voltages applied to its non-inverting and inverting inputs and produces a digital output based on the result of this comparison. When the voltage at the non-inverting input is higher than the voltage at the inverting input, the output goes high. Conversely, when the voltage at the inverting input is higher, the output goes low.
