DC offset dual rail battery supply 
  Can someone please have a look at this diagram and advise if it is workable? The object is to output two identical signals, one with a +12V shift above DC/GND, and the other a -12V shift. IOW there is a 24V differential between the mid-points of the two waveforms, with respect to each other, centered on the GND reference... more »

Ceramic Cap Ripple Current 
  I'm looking at this cap: [link] ND/930704 The only thing the data sheet says about the ripple current is that it is "high". So -- is there a way to tell just how much ripple current the cap will stand, short of buying 10000 of them and doing a study?... more »
