I build a proto with the recomandations mentioned in the previous posts.
Some measurements show that the DC/DC converter is suited for this kind of applications with the proper PCB design. However : the number of components needed is somewhat beyond any practical. 9V in => 5V regulator => PI filter => DC/DC converter => 2 x PI filter => neg./pos. regulator => RLC combination at powerpins opamp. But it can be done and that was one of the goals of this experiment. Thanks all for your input and help, Peter |
