Product Summary

The DM13A is a constant-current sink driver specifically designed for LED display applications. The DM13A incorporates shift registers, data latches, and constant current circuitry on the silicon CMOS chip. The maximum output current value of all 16 channels is adjustable by a single external resistor. The applications of the DM13A include Indoor/Outdoor LED Video Display and LED Variable Message Signs (VMS) System.
