Frequently Asked Questions
Does this driver include brightness correction for LEDs?
Yes, it offers dot correlation through 7-bit (128 steps) individual adjustment capability for each channel.
What steps must be taken during storage or handling of the device?
Due to limited built-in ESD protection, leads must be shorted together or the device placed in conductive foam.
What is the constant current output range per channel?
The channels support an adjustable constant-current sink ranging from 0 mA up to 80 mA.
How can I control the various functions of this driver?
Control is achieved via a serial data interface that is compatible with SPI and manages On/Off states and dot correction.
