Simulation of Op-Amp Summing Amplifier (Non Inverting) LT Spice

The non-inverting summing amplifiers using op-amp has been discussed along with the Vout and gain formula using LT Spice Tool
Non-Inverting operational amplifier circuit where the output voltage is proportional to the sum of the input voltages applied to its non inverting terminal The multiple inputs to non-inverting input terminal of the op-amp can be used as summing amplifier or adder circuit
Non- Inverting configuration, the inputs are applied at the non-inverting or + terminal of the op-amp.
Non- Inverting configuration, the calculation of the output voltage is getting complicated as the number of inputs increases. So to find Vout Superposition theorem needs to apply Non-inverting summing amplifier, the output voltage is always in phase with the input voltage.
Application of Summing Amplifier (Op-Amp):
1) It can be used for Digital to Analog Converter (DAC)
2) It can be used for Audio Mixer
