DESCRIPTION
The TLC5922 is a 16-channel constant-current sink
driver. Each channel has an On/Off state and a
128-step adjustable constant-current sink (dot
correction). The dot correction adjusts the brightness
variations between LED, LED channels, and other
LED drivers. Both dot correction and On/Off state are
accessible via a serial data interface. A single
external resistor sets the maximum current of all 16
channels.

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.
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.
