The PCA9922 is an 8-channel constant current LED driver designed for LED signage and
display applications. The output current is adjustable from 15 mA to 60 mA controlled by
an external series resistor. The outputs are controlled via a serial interface with a
maximum clock frequency of 25 MHz to allow for the system requirement of high volume
data transmission. Each of the 8 channel outputs has edge rate control to limit the change
in current when the outputs are enabled or disabled.
