Part Number: AFE4900 We have AFE4900 scaned with different TIA gain and LED driving current . as far as im concerned, the output code should rise as the gain and current rises, but it fails. The picture below shows our test result, the first and the second lane shows us the first and second LED1-ALED1VAL and LED2-ALED2VAL , and the 3 rd is the gain set by my firmware and the 4 th is the LED driving current . Would anybody tell me why and how 2 solve the problem pls? Thank you
