Working Principles

The TLC274CPWG4 is an operational amplifier that amplifies the difference between its two input voltages. It operates by using a differential input stage, followed by a gain stage and an output stage. The differential input stage amplifies the voltage difference between the non-inverting and inverting inputs, while the gain stage provides additional amplification. The output stage then drives the amplified signal to the output pin.
