This chapter focuses on linear amplifiers that achieve inverting, non-inverting, and summing. A widely used op-amp configuration is the inverting amplifier. A non-inverting amplifier can provide controlled voltage gain with high input impedance and no inversion of the input-output signals. A summing operational amplifier circuit can be used to add (calculate the sum) of input signal voltages. The inputs have individual voltage gains and can be either negative or positive. The internal construction of the op-amp cannot be altered. However, by connecting external electrical components, its overall operation can be modified. When the circuit is energized, it produces an AC output that drives a speaker load. If the circuit is functioning properly, the speaker will show that sound is being produced. The output AC waveform can also be observed on an oscilloscope.
