12:00 AM rue_mohr: maybe I should do both
12:05 AM rue_mohr: if I attenuate the dac by 5, and amplify the sense by 10
12:12 AM rue_mohr: hahaha
12:12 AM rue_mohr: its got an open collector output, so the datasheet says "output short to ground" = continious
12:12 AM rue_mohr: Output Short-Circuit to Ground
12:12 AM rue_mohr: (Note 2) Continuous
12:12 AM rue_mohr: :)
12:25 AM AchiestDragon: well yeas without an external pullup res on there
01:05 AM rue_shop3: the answer is no, the LM393 will NOT behave in the roll of an amplifier
01:30 AM mrdata: no?
01:30 AM * mrdata checks the datasheet
11:26 AM rue_bed: HMM
05:55 PM anonnumberanon: im not being very creative this end of year
06:42 PM Jak_o_Shadows: well, I cant' see any laws about flashing lights on houses in australia
11:35 PM rue_shop3: but it looks like, esp for inductive loads like the motors I want to run, that I can just use the comparitor to make the switching supply
11:36 PM rue_shop3: dont seem to need a flyback diode, dont need an output inductor
11:36 PM rue_shop3: just the dac, r-2r lm393 and fet driver
11:36 PM rue_shop3: 8-| huh.
