Working Principles

The LM324APWR is an operational amplifier that amplifies the difference between two input voltages. It consists of four independent amplifiers, each with a differential input stage and a push-pull output stage. The amplifiers are internally compensated to provide stable operation.

The input stage amplifies the voltage difference between the non-inverting and inverting inputs, while the output stage drives the output voltage based on this amplified difference. The amplifier operates by maintaining a virtual short circuit between its inputs, causing the output voltage to adjust accordingly.
