CXA2108AQ - Constant-Current Driver for Full Color LED Display

General Description

The CXA2108AQ is a 1,024-gradation LED driver which is ideal for full color LED displays.

This IC has 24 outputs and a maximum output current of 70mA.

Time division allows driving of either two or six LEDs per output by connecting an external FET or other switch.

Key Features

  • 24 outputs: 10-bit (1,024-gradation) PWM current outputs.
  • Maximum output current: 70mA.
  • LED type: Common anode.
  • 4-bit brightness function capable of switching the basic PWM pulse width in 16 steps.
  • Time division allows driving of up to six LEDs with a single output, making it possible to configure a high definition display with few driver ICs.
  • Coarse Adj. (2 bits) and Fine Adj. (8 bits) output current adjustment for each LED makes it possib.
