Description: 8-channel Constant Current LED

Features

* 25 MHz serial interface
* 3.3 V to 5.5 V operation
* 8 LED low side constant current outputs
* Global control for the 8 LED outputs variable between 15 mA to 60 mA
* 15 mA to 60 mA maximum current for all 8 output channels set by an external resistor

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 rat
