Lab#9Statement:To study the Non-inverting operational amplifier andcalculate its gain.Operational amplifier lab trainerDC power supplyDigital Multi-meterAC power sourceIC # 741Theory:Non-inverting amplifier means that its output and input voltage signals are in phase. In thisamplifier input signal is applied to non-inverting and feedback resistor R2is connectedbetween output and inverting terminal. For non-inverting amplifier rinis infinity in idealcase.If= Iin+ IBIf= Iin+ 0(Vo-VB)/Rf= (VB-0)/Rin(Vo/Rf) – (VB/Rf) = VB/Rin(Vo/Rf) = (VB/Rf) + (VB/Rin)V1=V2(Virtual Ground assumption)VB= VinV0/Rf= Vin/Rf+ Vin/RinVo= Vin(Rf/R1+ 1 )Rf= Rin= 1KΩVo= Vin(1+1)Vo= 2 VinProcedure:First of all I took a DC power supply and DMM. After this I applied +12V to +Vcc
