Please note: Yodel is currently experiencing issues. Whilst the issue is ongoing, orders placed using this service will be dispatched via Evri or Royal Mail 48 hour service.
The DM13A 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.
