DM632 16-CHANNEL CONSTANT CURRENT LED DRIVER

DM632 is a 16-channel constant current sink LED driver. Each channel has adjustable 16-bits (65536 steps) grayscale PWM control current outputs. It incorporates shift registers, data latches, constant current circuitry with current value set by an external resistor, selectable oscillator source for .
