Each channel has an On/Off state and a 128-step adjustable constant-current sink (dot correction).
The dot correction adjusts the brightness variations between LED, LED channels, and other LED drivers.
Both dot correction and On/Off state are accessible via a serial data interface.
A single external resistor sets the maximum current of all 16 channels.
