DM164
Description
The DM164 is a LED current sink driver incorporating independent shift registers and data latches for grayscale PWM data (GD mode*1) and current adjustment data (D&G mode*1), 8x3-channels constant current circuitry with current value set by 3 external resistors, 65,536 grayscale PWM function unit, 128 levels current adjustment for each channel and 256 levels global brightness control (White balance). Each channel provides maximum current of 90mA.
