In this circuit, Op-Amp operates in the closed loop. Input is applied to the Inverting terminal and output is fed-back to the inverting terminal as voltage shunt feed-back. The polarity of the output voltage is opposite to that of the input. Below is the circuit diagram of inverting amplifier with Dual voltage supply conditions.
Op-Amp as Inverting Amplifier
Inverting amplifier configuration can give unity gain, i.e., Vout=-Vin. The output varies according to gain of the amplifier circuit between +Vsat and -Vsat. So, selection of supply voltage range is important to obtain the desired output voltages. Output of the Op-Amp follows the equation,
