> 1. I've read that each channel can output 120mA- does this mean that it can output 16 x 120mA all at once?That's what my reading of the datasheet would indicate. You have to feed the chip more then 3.6V to get 120 mA out. At lower voltage it's 60 mA.
does this mean that it can output 16 x 120mA all at once?
As for the power dissipation the TLC5940 datasheet say's it has a power dissipation of 2.5W- fungus you stated 1.5W is this just incoraporating a safety margin?
Ah ok! Thanks for clarifying that fungus! I'll definately be putting a resistor on each LED.http://led.linear1.org/led.wiz says that a 15ohm resistor on each LED will dissipate 216mW per resistor which I guess leaves the TLC hardly anything to dissipate- does that soudn right to you?
