DESCRIPTION
The TLC59482 is a 16-channel, constant-current sink
driver. Each channel has an individually-adjustable,
pulse width modulation (PWM) grayscale (GS)
brightness control with 65,536 steps. All channels
have a 64-step global brightness control (BC). BC
adjusts brightness deviation with other LED drivers.
GS and BC data are accessible via a serial interface
port.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
