The LED2472G guarantees 20 V of output driving capability, allowing several LEDs to be connected in series. The device is configured in 3 groups (red, green and blue) of 8 independently-controlled channels. The LED current can be separately regulated for each color within the range from 4 mA to 72 mA. This range is divided into two sub-ranges and the current can be adjusted within each range in 64 steps of resolution (6 bits per color). A single external resistor is required. All the controls and the shift registe...
