Working Principles

The EL2250CS is a voltage feedback operational amplifier that amplifies and conditions electrical signals. It operates by taking the difference between the voltages at its non-inverting and inverting inputs and amplifying this difference to produce an output voltage. The gain of the amplifier can be adjusted using external resistors connected to the feedback loop.
