DM137 Datasheet (SiTi) - 16-bit Constant Current LED Driver

DM137, 16-bit Constant Current LED Driver

DM137 is a constant-current sink driver specifically designed for LED display applications.

The device 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.
