8-bit Constant Current LED Driver

General Description

      DM11A 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 8 channels is adjustable by a single external resistor.

Features

• Constant-current outputs: 3mA to 60mA adjustable by one external resistor

• Maximum output voltage: 17V

• Maximum clock frequency: 25MHz

•  Power supply voltage: 3.3V to 5V z In-rush current control

• Output slew rate control (Tr/Tf, over/under shoot) 

• Bit-to-bit skew : ± 3 % (max.) Chip-to-chip skew : ± 6 % (max.) 

• Package and pin assignment compatible to conventional LED drivers (DM114/5/6)
