The applied input to the respective terminal decides whether it … The above figure shows the circuit diagram of an ideal inverting amplifier. It is widely used in audio mixer and many other applications where voltages need to be summed. A summing amplifier is an inverted OP-Amp that can accept two or more inputs. An OP-AMP IC may contain two dozen transistors, a dozen resistors and one or two capacitors. The goal of this text, as its name implies, is to allow the reader to become proficient in the analysis and design of circuits utilizing modern linear ICs. For example, an operational amplifier may not be fit for a particular high-gain application because its output would be required to generate signals outside of the safe range generated by the amplifier. An additional 180 degrees phase shift is obtained because of the RC feedback network. Fig.1 shows a three-input summing amplifier. Additionally, current drawn into the operational amplifier from the power supply can be used as inputs to external circuitry that augment the capabilities of the operational amplifier.
