Well, after getting the ssop adapters and spending an entire evening trying to solder one of my dm132 chips to it, I've discovered that the chips seem not to be standard ssop 28!! The "legs" are not wide enough, in the ssop 28 standard it says the minimum chip width and minimum width including the legs is 5mm and 7.4mm respectively, but the dm132 is 4mm wide and 6.7mm! So the adapters do not work! After a lot of consideration, i've decided to bite the bullet and get the tlc5940 chips from texas instruments which are about twice as expensive..BUT, apart from the fact that they come in standard DIL package, there seems to be a lot more documentation and discussion about them online, which can not be said for the dm132.. |
