*1 The amount of current per channel.
*2 If LED makes significant variations in its reference voltage, the driver will increase power dissipation, resulting in a rise in package temperature.
To avoid this problem, design the board with thorough consideration given to heat radiation measures.
*3 The range which the LED current changes with linearity is from 1.5V to 5V.
