Two pins are for power supply such as Vcc- and Vcc+. In short, this table lists the descriptions of all pins.

it is to be kept open LM741 Op-Amp Electrical Features PINS Details 1 ( Offset N1) Offest pin 1 is for external input offset voltage adjustment 2 ( Inverting Input) Inverting input for applying the inverting input voltage 3 (Non-Inverting Input) Non- inverting input pin for applying a non-inverting input voltage 4 (-Vcc) Vcc- is for applying negative DC supply 5 (Offset N2) Offset Null 2 is for external input offset voltage adjustment 6 (Output) Output pi is for obtaining output voltage 7 (+Vcc) Vcc+ is for applying positive DC supply 8 (NC) This pin is for no connection i.e. In this section, we discuss the electrical specifications. One of the main features of this op-amp is overload protection. Unlike other op-amps, it has the following features: On top of that, it supports overload protection for inverting and noninverting pins. Potentiometers are rarely used to directly control significant power (more than a watt), since the power dissipated in the potentiometer would be comparable to the power in the controlled load. Potentiometers comprise a resistive element, a sliding contact ( wiper) that moves along the element, making good electrical contact with one part of it, electrical terminals at each end of the element, a mechanism that moves the wiper from one end to the other, and a housing containing the element and wiper. The op amp offset null capability is one that is available on many op-amp chips. The offset null capability is used to reduce small DC offsets that can be amplified. These can be important in DC amplifiers where these small voltages can then become significant where large gains are required.

Op amp input offsetsĪn op amp is a differential amplifier. This means that when there is no difference between the two inputs, e.g. When the inputs are shorted together, there should be no voltage on the output.
