LM741 op-amp voltage follower 741 is used as the circuit with 18 resistance opamp output voltage is taken from the referents by the formation of the symmetrical voltage is converted into 0-end circuit has been tested by me. For a voltage follower circuit the gain should be made unity, to make the gain unity, consider the non-inverting configuration of the op-amp.To satisfy this condition, the operational amplifier should satisfy ideal condition. The circuit shown below is of a sample and hold circuit based on uA 741 opamp , n-channel E MOSFET BS170 and few passive components. In the circuit MOSFET BS170 (Q1) works as a switch while opamp uA741 is wired as a voltage follower. The lowest gain that can be obtained from a noninverting amplifier with feedback is 1. When the noninverting amplifier is configured for unity gain, it is called a voltage follower because the output voltage is equal to and in phase with the input. Note the load resistance and capacitance are shown in the circuit to represent a load and are not necessarily part of a voltage follower circuit.The Lm741 was used in this example just to represent the fact that any Op Amp could fill the roll.
