带有点校正的 16 通道 LED 驱动器
The is a 16-channel constant-current sink driver. 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.
