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

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)
