Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?
Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?
(OP)
USB-1208FS supplies 5v I believe so can it supply that much to the LED driver which is running 13 Bi-colour LEDs
Thanks
Thanks

In any case, the output current of the analog output is only 6mA, which is usually too little for LEDs, but since you've not posted any information about the LEDs, so who knows?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

is that output current of the analog output from the DAQ? which is 6mA

RE: Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?
So is there anything I can do to get the current to drive the 13 Leds? but not all of them will be on at the same time only 1 will be on as the next on in line blinks
here is the datasheet for the LED driver http://www.datasheetlib.com/datasheet/241919/gm648...
Thanks for the help I really appreciate it

Doesn't it say if it's connected through a usb to pc there is 500mA ( under power subheading page : 25 )
RE: Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?
On the first page.
The power of the USB port has nothing to do with whether the DAQ can drive LEDs. Unless you are simply using the Vcc connection only, but then, what's the point of the DAQ?
Is the driver in addition to the DAQ, or instead of the DAQ? In either case, you've picked a driver than can only supply 15 mA

How will the LEDs receive current in this case which they need to be able to work?
I thought the DAQ might provide current as well but maybe I am mistaken, I know the LED driver provides current so that only provides 15mA and I need 20mA for the LEDs to work, any way I can make them work?
Thanks really appreciate this.

RE: Can DAQ power a 33 output LED Driver which is driving 13 Bi-colour LEDs?
Yes that is what I am planning to do have two outputs for each LED,as it is a bi-colour LED so current will run through each leg of the LED to determine which colour should be displayed, will this be able to make the LEDs work?
Thanks
