AS1108 LED Driver IC

4x8 Matrix LED driver IC


The AS1108 is a, SPI interfaced, dot-matrix LED driver IC for a 4x8 LED matrix or 4 7-Segment LEDs. It includes a 4bit PWM for the entire matrix and an external resistor can be used for analog current adjustment up to 10mA per LED.


Key Features

  • Up to 32LEDs in a 4x8 matrix
  • 4bit PWM and resistor current control per matrix
  • BCD decoder

Key Benefits

  • Drive high LED count very easily
  • Brightness adjustment of the matrix
  • Allows decoding for 7-Segment LEDs
