SD16729
16-BIT CONSTANT CURRENT LED DRIVER
DESCRIPTION
SD16729 is a constant current LED driver with advanced Bi-CMOS
technology, the constant current is determined by external resistor.
It includes a 16-bit shift register, latches, the constant current driver
and etc. In the output stage, there are 16 current sources which
provide a 1-45mA constant current drive for LED through bipolar
device.
