TLC5940 Datasheet (Texas Instruments)

TLC5940, 16-Channel LED Driver

The TLC5940 is a 16-channel, constant-current sink LED driver.

Each channel has an individually adjustable 4096-step grayscale PWM brightness control and a 64-step, constant-current sink (dot correction).

The dot correction adjusts the brightness variations between LED channels and other LED drivers
