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. The dot correction data is stored in an integrated EEPROM. Both grayscale control and dot correction are accessible via a serial interface. A single external resistor sets the maximum current value of all 16 channels.</p> <p><b>Packages:</b> <ul><li>28-pin HTSSOP <li>32-pin 5x5mm QFN <li>28-pin DIP</ul></p> Packages: PWP TLC5940 TSSOP28-GROUNDPAD tssop28-groundpad sparkfun LED Driver TLC5940 pwp BLANK
