A summing amplifier is a type of operational amplifier circuit that combines multiple input voltages into a single output voltage. There are two main types: inverting and non-inverting. The inverting configuration is most common as it provides low distortion by forcing the signal to swing around ground. Summing amplifiers are used to add signals in applications like audio mixers and converting digital to analog signals.

WHAT IS A SUMMING AMPLIFIER? The Summing Amplifier is a type of operational amplifier circuit that is used to combine several input voltages into a single output voltage. If we connect many input terminals along with the input resistor in parallel to the existing input terminal, we get another amplifier called a summing amplifier.
APPLICATIONS OF SUMMING AMPLIFIER •Used in an audio mixer •Used to add the signals •Convert digital signal to analog signal •It can change a binary number to a voltage in an AC
TYPES OF SUMMING AMPLIFIER Summing Amplifiers are basically of two types- 1. Inverting Summing Amplifier 2. Non Inverting Summing Amplifier
INVERTING SUMMING AMPLIFIER The inverting op-amp configuration is the most widely used constant gain op-amp configuration. •Why do we need inverting amplifier? 1. For polarity inversion with or without gain 2. Low distortion due to no common-mode component (signal is forced to swing around ground due to summing node) 3. Adding inputs to make a summing amp.
DERIVATION OF INVERTING SUMMING AMPLIFIER
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
DERIVATION OF NON INVERTING AMPLIFIER USING 2 DIFFERENT INPUT VOLTAGES
DERIVATION OF NON INVERTING AMPLIFIER USING 3 DIFFERENT INPUT VOLTAGES
