If you connect a steady voltage to the input terminal, the output voltage will be equal to the input voltage multiplied by some number, with no change in polarity. The only design criteria that must be chosen is that the non-inverting amplifier must possess the high value of the impedance at the input. In this configuration, the input voltage signal, ( VIN ) is applied directly to the non-inverting ( + ) input terminal which means that the output gain of the amplifier becomes Positive in value in contrast to the Inverting Amplifier circuit we saw in the last tutorial whose output gain is negative in value.
