Texas Instruments TLC5942
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. Both grayscale control and dot correction are accessible via separate, dedicated serial interface ports.| Part No. | TLC5942 |
