AndrewCE Posted January 4, 2009 Report Share Posted January 4, 2009 An Op Amp Voltage Buffer, a.k.a. Voltage Follower, is when you connect the output of an op amp directly to the inverting input. The voltage at the noninverting input is copied directly to the output. But there is infinitely high input impedance and infinitely low output impedance. Google it for more info. So here's the Question: Say you've got a voltage source, "A", before the Voltage Follower. In parallel with all of that, you've got another voltage source, "B". How does B affect the operation of the voltage buffer? Would the 2 voltages just be added? Would the total output just be equal to B or A? Would B invade the inverting input and get saturated? I ask because I am considering using op amps in some active circuitry in my guitar. Quote Link to comment Share on other sites More sharing options...
