    Current Controlled Current Source Help Maybe other things?

    Yea, but I only have a finite number of the IC's :(. I'm trying to make an RGB matrix of 25 squares for an interactive table. I'm already having to control 75 (3 colors per square) LED's. I think 300 different inputs would make my brain fry.

    Current Controlled Current Source Help Maybe other things?

    So, I think I've figured it out: Since the IC is PWM, the current is always 0 or 20mA. I can just use a resistor and turn this into a Voltage source that varies between 0 and some static value that I want. I can then use this voltage source to drive a different constant current source...

    Current Controlled Current Source Help Maybe other things?

    Yes: I want to drive 4 tricolor LED's in series. But in order to drive them in series don't you need to connect A-C-A-C...etc. and since they share a common anode wouldn't that make it impossible? I would like them to be in series because I want to four LEDs to be functionally one single, very...

    Actually, this doesn't even need to be variable, it just needs to be able to amplify the current to 80mA because it's PWM, sorry wasn't thinking.

    Current Controlled Current Source Help Maybe other things?

    Hey, So I'm making a really cool RGB LED project, and I need four of the RGB's to be in series. Now, as I understand this it's impossible since all three share an Anode. The LED's are going to be controlled via MAX6966, it's a PWM constant current source for the LEDs. I'm treating this...
