Texas Instruments TLC5951 24-Channel Constant-Current Sink Driver comes with each channel having an individually-adjustable, 4096-step, pulse-width modulation (PWM) grayscale (GS) brightness control. The device also includes a 128-step constant-current dot correction (DC). The dot correction adjusts brightness deviation between channels and other LED drivers. The output channels are grouped into three groups of eight channels. Each channel group has a 256-step global brightness control (BC) function and an individual grayscale clock input. GS, DC, and BC data are accessible via a serial interface port. DC and BC can be programmed via a dedicated serial interface port.
