In this video, the inverting
In this video, the inverting and the non-inverting summing amplifiers using op-amp has been discussed along with the derivations.
In this video, it has been discussed that how by applying multiple inputs to either inverting or the non-inverting input terminal of the op-amp, it can be used as summing amplifier (as adder circuit)
Inverting Summing Amplifier:
In this configuration, the inputs are applied at the inserting end of the op-amp.
The advantage of this configuration is that each individual inputs are isolated with respect to each other and there is no interference or cross-talk between the different input voltages. (because of virtual ground)
However, the output voltage is inverted with respect to input voltage. And it can be further inverted by using one more inverting op-amp with unity gain at the output of the summing amplifier.
In most of the practical applications, this inverting summing op-amp is used.
Non-Inverting Summing Amplifier:
In this configuration, the inputs are applied at the non-inverting end of the op-amp.
In this configuration, the calculation of the output voltage is getting complicated as the number of inputs increases. Moreover, there is cross-talk between the different inputs. (Inputs are not isolated with each other)
In non-inverting summing amplifier, the output voltage is in phase with the input voltage.
Application of Summing Amplifier:
1) As voltage adder, scaling, averaging circuit
2) To provide the DC offset to the input signal
3) Digital to Analog Converter (DAC)
4) Audio Mixer
The timestamps for the different topics is given below:
0:51 Inverting Summing Amplifier
4:48 Scaling and Addition using Summing Amplifier
5:29 Averaging operation using Summing Amplifier
6:40 Application of summing Amplifier
9:26 Non-Inverting Summing Amplifier (with two inputs)
12:51 Non-Inverting Summing Amplifier (with three inputs)
