MY9942
4 Channels Constant Current LED Driver With
Addressable DMX512 Protocol and Differential Interface
General Description
Features
The MY9942, 4 channels constant current LED driver with 14bits grayscale APDM (Adaptive Pulse Density Modulation) control, supports standard / 4X DMX512 protocol and fully differential interface suited for long distance parallel applications. The distinctive DMX512 decoding approach could decode precisely a standard DMX512 signal. And each device loads one/two/three/four grayscale data according to two slot selection pins and nine address setting pins (512 addresses). The differential interface provides wide common-mode range to support long distance transmission without common-ground power systems.
