BUF634 Power Supply

post #1 of 2
Thread Starter 
Hey Guys,

When building a BUF634 power supply for use in a CMoy amp is it best to place the BUF after the bypass capacitors in the power supply or before them?

Or does it really make no difference?

Edit: With regard to decoupling power supply pins at Op Amps, should i also decouple the BUF634 power supply pins, not in the power supply but those BUFs after the gain stage? Would a 0.1uF bypassed with a 100uF Electrolytic be OK for this?

Thanks

When using the BUF-634 as a Virtual gnd Driver I Bypass this Localy with 0.1uF caps as well as use Local Bypass caps on each Opamp and Buffer in the Amp. The Electrolytics can be located some distance from the IC's but each should have small Film types located as close to the Supply pins of each Chip as Possible.
