Op amp - Study guides, Revision notes & Summaries

Voltage Divider Law - Vout = (Resistors between V and ground)/(R total) * Vin Rpot + voltage divider - Rpot = R1 + R2 Op amps have a ______ input impedance and a ______ output impedance. - high low What does an op amp having a high input impedance mean - zero current into V+ and VWhat property of the op amp allows it to act as a buffer? - low output impedance and high input impedance isolate blocks of circuits

Audio signals, such as the output from DVD players, satellite receivers and preamplifers, usually are of what amplitude for input to a TV, modulator or other equipment? - 1 voltage peak to peak The gain of an op-amp is directly, but inversely, related to bandwidth as input frequency increases: - Always Applying positive voltage to the P end and negative to the N end of a germanium diode: - will forward bias it Some variable capacitors are made so the plates interleave. The capacitance vari...

I*R - V (Ohm's Law) = comparator - What is the mode of this op-amp? Vin*(R2/R1+R2) - Vout for voltage divider = Amplifier - What is the mode of this op amp circuit? -Vin*(Rf/R1) - The output voltage of an amplifier circuit can be given as Vout = Inverting Summer - What is the name of this op-amp circuit?
