 What is a key feature of the inverting amplifier? That both the input signals and the feedback are applied at the inverting terminal of the op amp For an ideal op amp the voltages and current are? Voltages: V1 = V2 Current: I1 = I2 == 0 An inverting amplifier ________ the polarity of the input signal while __________ it. Reverses Amplifying The voltage gain of a inverter is? Av = Vo/Vin = -Rf/R1 Vo = (-Rf/R1)(Vin) If the gain is the Rf/R1 the gain depends only on the external elements connected to the op amp The inverting amplifier is used, for example, in a _______ converter Current-to-Voltage input voltage is applied directly to the noninverting input and resistor is conected between the ground and inverting terminal. What type of Amplifier Noninverting Amplifier The voltage gain of a noninverter is? Av = Vo/Vin = (1+Rf/R1) Vo = (1+Rf/R1)(Vin) An noninverting amplifier is an op amp circuit designed to provide a _______ voltage gain Positive On a noninverting amplifier If the feerback resistor Rf = ___ Or R1 = ____ Or Both the gain becomes 1. Rf = 0 (short circuit) R1 = infinity (open circuit) AuthorRayen ID48463 Card SetOSU ENGR201 DescriptionOSU ENGR201 material 2010 Updated2010-11-09T18:40:28Z Show Answers
