• Manufacturer Part Number: DM11C
• Description: 8-bit Constant Current LED Driver with Error Detection
• Manufacturer: SITI [Silicon Touch Technology Inc.]

Outputs Delay
this effect, DM11C is designed to have a constant unit of delay (around 1.5ns) between every output.
The delay for every output goes like this: there is no delay for OUT7, 1 unit of delay for OUT6, 2
units of delay for OUT5 and so on.
Global Brightness Control
of global brightness control effect, two methods could be utilized. One is providing PWM signal
synchronized on latch pulse to modulate the output enable terminal (EN pin). The other is to adjust
the Rrext value or voltage drop across the external resistor. Please see the reference circuit below:
8-bit Constant Current LED Driver with Error Detection
Large in-rush currents will occur when the system activates all the outputs at once. To reduce
DM11C has no built-in global brightness control feature. In order to obtain a lower resolution
