DESCRIPTION
The LD1018 is specifically designed for LED display applications. The constant current output can be preset through an external resistor (IOUT = 3mA to 45mA). The device consists of 16bit shift register, latch and constant current output driver. The LD1018 provides a constant output current for driving the LEDs against for the variation of LED forward voltage( Vf ).
The LD1018’s excellent current matching characteristics among the output ports and fast output response time will give you the best display quality for LED display system.
