In this lesson we discuss the non-inverting operational amplifier circuit. One of the basic configurations of operational amplifiers that has a non-inverting gain (which does not change the polarity of the output signal in relation to the input signal) and an infinite input impedance. It is a topology widely used in signal conditioning and processing circuits and electronic instrumentation. Previous lesson: • Inverting Amplifier Amplifier ...
