Analyze Inverting Op Amp Circuits dummies An inverting amplifier takes an input signal and turns it upside down at the op amp output. When the value of the input signal is positive, the output of the inverting amplifier is negative, and vice versa. Here is an inverting op amp. The op amp has a feedback resistor R 2 and an input resistor R 1 with one end connected to the voltage source. Op Amp Gain Explanation Calculation Equation ... Inverting op amp gain. The circuit for the inverting op amp circuit is shown below. This circuit has the output 180° out of phase with the input and also provides a virtual earth input. The circuit is quite straightforward using a single feedback resistor from the output to the inverting input, and a resistor from the inverting input to the input of the circuit. The non inverting input is taken a ground point. Basic inverting operational amplifier circuit Non inverting Operational Amplifier Configuration In this configuration, the input voltage signal, ( V IN ) 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. The result of this is that the output signal is “in phase” with the input signal. Summing Amplifier is an Op amp Voltage Adder As its name implies, the non inverting summing amplifier is based around the configuration of a non inverting operational amplifier circuit in that the input (either ac or dc) is applied to the non inverting ( ) terminal, while the required negative feedback and gain is achieved by feeding back some portion of the output signal (V OUT) to the inverting ( ) terminal as shown. Op amp Integrator, Operational Amplifier Integrator Since the capacitor is connected between the op amp’s inverting input (which is at earth potential) and the op amp’s output (which is negative), the potential voltage, Vc developed across the capacitor slowly increases causing the charging current to decrease as the impedance of the capacitor increases. Op amp parator and the Op amp parator Circuit With reference to the op amp comparator circuit above, lets first assume that V IN is less than the DC voltage level at V REF, ( V IN < V REF ). As the non inverting (positive) input of the comparator is less than the inverting (negative) input, the output will be LOW and at the negative supply voltage, Vcc resulting in a negative saturation of the output.
