Hey all, I currently have LED numeric displays that are being driven by an old UDN2585 8 channel source driver and a 100 Ohm resistor network. I'm trying to replace it with some new drivers, but the displays now are just on all the time without actually displaying a number. Does this mean there is too much current going into the LED displays? If so, would changing the 100 Ohm resistor network to a different value possible fix this?
Thank you so much for any possible.
