TLC5942 - 16-Channel 12-Bit PWM LED Driver

Description

The TLC5942 is a 16-channel, constant current sink driver.

Each channel is individually adjustable with 4096 pulse-width modulated (PWM) steps and 128 constant current sink steps for dot correction.

Dot correction adjusts the brightness variations between LEDs.
