OPT3001-Q1: reg value is not linear and unstabe with the same light

Part Number: OPT3001-Q1

Hi team,

customer test the OPT3001-Q1, have two problems. one is that the reg value can't stable under the same light. two is with the light increase, the reg value is not linear.

can you help to check it wheter any mistakes at this design? thank you

bleow is schemaic and reg configur, also the comapre tabel between another light sensor and OPT3001-Q1.

Start();

Write(0x88);

Write(0x01);

Write(0xC6);

Write(0x10);

 Stop();

For the scheamtic, the SDA and SCL have add 10kohme pull up resistors.

the left is another light sensor, the right volume is TI OPT3001-Q1. you can see taht with the light increase, another sensor value is increase postively, but the OPT3001-Q1 value is sometimes big, and sometimes small.
