TLC5944 - 16-Channel 12-Bit PWM LED Driver

General Description

The TLC5944 is a 16-channel, constant current sink driver.

Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 64 constant sink current (dot correction) steps.

The dot correction (DC) adjusts for brightness variations between LEDs.
