MY-Semi Preliminary MY9941 4 Channels Constant Current LED Driver With Cascade DMX512 Protocol and Differential Interface General Description Features The MY9941, 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 cascade 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. The differential interface provides wide common-mode range to support long distance transmission without common-ground power systems.
