Product Descriptions

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 PWM functioning, and built-in LED open detection circuit to detect error status. It is specifically designed for LED display or lighting applications.
