Working Principles

The LM2901AQS14-13 compares the voltages applied to its input pins and provides digital outputs based on the comparison results. Each comparator within the IC operates independently, comparing the voltage at its inverting input (INx) with the voltage at its non-inverting input (VCC/2). When the voltage at the inverting input is higher than the voltage at the non-inverting input, the output goes low (logic 0), and when the voltage at the inverting input is lower, the output goes high (logic 1).
