Working Principles
The MC1458D is an operational amplifier that amplifies the difference between two input voltages. It consists of two independent op-amps in a single package. The op-amp operates by comparing the voltage at its inverting input (Vin-) with the voltage at its non-inverting input (Vin+). The output voltage is then amplified based on the difference between these inputs.
