This video covers the OpAmp ic 741.Also provide notes.

OP-AMP: An operational amplifier (or an op-amp) is an integrated circuit (IC) that operates as a voltage amplifier. An op-amp has a differential input. That is, it has two inputs of opposite polarity. An op-amp has a single output and a very high gain, which means that the output signal is much higher than input signal.

POWER DESIPIATION:- The process in which an electric or electronic device produces heat (other waste energy) as an unwanted byproduct of its primary action.

OFFSET VOLTAGE:-Input offset voltage is defined as the voltage that must be applied between the two input terminals of an OPAMP to null or zero the output(output given by circuit even if there is no input applied ,it happens due to mismatching in transistor).
