The non inverting amplifier configuration is one of the most popular and widely used forms of operational amplifier circuit and it is used in many electronic devices. Typical digital buffer ic s available are the 74ls125 quad 3 state buffer or the more common 74ls244 octal buffer. The op amp non inverting amplifier circuit provides a high input impedance along with all the advantages gained from using an operational amplifier.
This is where you will place the incoming input signal.
And the formula to calculate the gain of a non inverting amplifier is. Therefore for a non inverting amplifier circuit the input impedance is given by the equation z in 1 a ol a cl z i. Notice that the input is applied to the non inverting input while the feedback is applied to the inverting input. The non inverting amplifier is the basic circuit obtained from amplifiers.
