Note:

1. Gains selections, GS: Bit 2 Bit 1 Bit 0 are applicable for each Red,

Green and Blue Channel.

2. Gain selections for each channel can be selected independently

of each other.

3. Feedback resistor value is proportional to responsivity. Refer to

block diagram below.

4. 0 indicates that the pin is connected to ground. 1 indicates no

connection.
