DESCRIPTION
The AA1726 is a low voltage; low current and constant-current drivers designed for LEDs and LED displays. The output current can be set using an external resistor. As a result, all outputs will have virtually the same current levels. This driver incorporates a 16-bit constant current output, a 16-bit shift register, a 16-bit latch and a gate circuit. The full-scale constant output current of each channel will range from 5mA up to 90mA.
