Output equation of Non-Inverting Amplifier Simulation of Op-Amp as Non-Inverting Amplifier Output of the Op-Amp follows the equation, But, Non-Inverting configuration cannot give gain less than or equal to unity. So, selection of supply voltage range is important to obtain the desired output voltages. The output varies according to the gain of the amplifier circuit up to V sat. Below are the circuit diagrams for Single as well as Dual voltage supply conditions. The polarity of the output voltage is same as that of the input. Input is applied to Non-Inverting terminal and output is fed-back to the Inverting terminal as a voltage shunt feed-back. In this circuit, Op-Amp operates in a closed loop. When V+ < V- the output=4V which is Logic High state. The voltage at the Non-Inverting and Inverting terminals (pins) i.e., V+ and V- are compared, and if V+ > V- then output is +V sat and if V+ V- the output=1.49V which is Logic Low state. The basic application of an Op-Amp is to use it as a voltage comparator. Some of the basic operation modes and application circuits are presented here.ħ41 Op-Amp description in Proteus Op-Amp as a Comparator The frequency of operation, slew rate and voltage ranges are the key parameters to select the right Op-Amp. ![]() For example:- 741 has single Op-Amp and LM 324, LM 339 have 4 Op-Amps each. Op-Amps in different IC packages are available.
