Description: 9-Channel 64steps Constant-Current LED Driver

Features

* 9 channel constant-current outputs, up to 40mA each
* Each channel current could be controlled through a SPI interface with MCU
* Power-On Reset(POR), all register bits=0
* For common-anode LEDs
* High data input rate: < 20MHz
* 2.7V to 5.5V Supply V

Applications

* The max output constant current can be set using an external resistor, and 64 steps of current could be set through a SPI interface with MCU. Any channel output could have any step current levels.
