Low Power 16-bit Constant Current LED Driver

General Description

DM13A-E 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.

Features

 Minimum constant-current outputs: 0.3mA

 Low minimum output voltage: 0.31V@0.4mA

 Maximum output voltage: 5.5V

 Maximum clock frequency: 25MHz

 Power supply voltage: 3.3V to 5V

 Overshooting stress elimination

 Ghost elimination

 In-rush current control

 Bit-to-bit skew :  0.7 %@0.8mA

 1.1 %@4.5mA

 2 %@15mA

 Chip-to-chip skew :  1.4 %@15mA

 Package and pin assignment compatible to conventional LED drivers (DM13A exclude QFN24)

Applications

 Indoor LED Video Display

Package Types

 DIP24, SOP24, SOP24B, SSOP24, QFN24
