AA1726中文资料16-bit Constant Current LED Driver数据手册Agamem规格书

描述 Description

The AA1726 is a low voltage, low current and constant-current drivers designed for LEDs and LED displays. The outputcurrent 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 gatecircuit. The full-scale constant output current of each channel will range from 5mA up to 90mA.
