Op amp power equation
Web1 de dez. de 2011 · The power consumption is calculated from the circuit current of the operational amplifier itself and from the output load current. Examples of when the output current flows out and flows in are shown below. (1) Output current flowing out (2) Output current flowing in For example, the power consumption in the case of the above … WebWhen an op amp operates in linear (i.e., not saturated) mode, the difference in voltage between the non-inverting (+) and inverting (−) pins is negligibly small. The input impedance of the (+) and (−) pins is much larger than other resistances in the circuit.
