#158895 - voltage follower Responding to: ???'s previous message |
See link for voltage follower.
http://hyperphysics.phy-astr.gsu.edu/Hbase/ele...pvar2.html Another thing: A voltage follower have very high input impedance, depending on type of OP used. You may want to have a resistor from input to ground to avoid having the voltage follower working as an antenna. I built a pre-amp and forgot to solder the input resistors. With the tape player connected to one input and the other inputs open, I could listen to the music from the tape recorder on any input. With no cable at all connected, I could listen to Radio Luxemburg (which happens to be what a radio close-by was tuned to). |

| Good link that.. | 01/01/70 00:00 | |
| Wont work | 01/01/70 00:00 | |

| Thanks. | 01/01/70 00:00 | |
| I would eventually omit the input buffers... | 01/01/70 00:00 | |
| Now that is worrying.. | 01/01/70 00:00 | |
| What I meant... | 01/01/70 00:00 | |
| Inputs swapped | 01/01/70 00:00 | |
| Extremely sorry for the goof up. | 01/01/70 00:00 | |
| Some hints... | 01/01/70 00:00 | |
| Just in time... | 01/01/70 00:00 | |
| As long as... | 01/01/70 00:00 | |
| Yes I understand. | 01/01/70 00:00 | |
