Whats the best way to run multiple analog circuits on one AC-DC converter?

I want to power a number of individual op amp circuits on a single AC-DC supply. I'm just wondering if its ok to just tie them directly together on the same branch or should I add something to regulate it. the supply can put out 500mA and each circuit is 12mA so I figure it shouldn't be a problem right? or should I put some series resistors on each unit to regulate the current?Whats the best way to run multiple analog circuits on one AC-DC converter?
No, you do NOT want to regulate the current. Why would you do that?



As long as the circuits can share a common ground as well as a common supply, you should be fine. Be sure to put a good sized bypass cap on each circuit, say at least 50碌F at 25 volts. As well as 0.1碌F bypass caps on each component. Use heavy gage wire, say #20, to connect the grounds.



If you have interactions problems, add a small resistor in series between each circuit and the supply +, say 22 ohms.
