Where do I connect 5.75V to in order to blow the fuses, AVDD, DVDD, VCLAMP or a
combination of these?


Typically VCLAMP and DVDD set to the same voltage as AVDD, to avoid having
supplies. The fuse blow current flows between the AVDD and AVSS pins, so these
should be decoupled with a 100nF ceramic/polyester in parallel with a 10uF
ceramic/tantalum (as close as possible to the pins).
