1.3 Specification

The LP5890 device supports per-channel current from 0.2mA to 20mA, with typical 1% channel-to-channel current deviation and typical 1% device-to-device current deviation. The DC current value of all 48 channels is set by an external IREF resistor and can be adjusted by the 8-step global brightness control (BC) and the 256-step per-color group brightness control (CC_R/CC_G/CC_B).
