SD16729 is a show dedicated to the constant current LED driver. The constant current value of the external resistor value can be determined. This circuit, including a 16-bit shift registers, latches, the current drive, and the use of advanced Bi-CMOS process. In the output stage, there are 16 current source, bipolar device, with a 1-50mA constant current drive for LED.
