TLC5923 16-CHANNEL LED DRIVER

The TLC5923 is a 16 channel constant-current sink driver. Each channel has a On/Off state and a 128step 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 resi.
