I'm looking for a dc offset trim circuit for the BUF-634 .
I have worked up a simple unity gain line buffer with it but the dc offset on the input/output is horrible.
I would like to stay away from any capacitor coupling.
Any suggestions would be much appreciated. |

There are probably several ways. Assuming the offset is stable you may consider applying a similar dc voltage of opposite polarity at the input. Or use an inverting dc servo.
I personally think that the 634 sounds worse than most caps anyway. |
