About EVAL-ADPD1081

Q1 Is following soft fair firmware a latest version?
  Warning indicates "This firmware isn't being supported."
   Tool :1.8.5.3
   motherboard:3.5.0

Q2 Please tell me a relation between the biggest scale in vertical axis Amplitude of a chart and the number of bits.

Q3   

After loading ADPD108_M07 in ADPDconfig, it's in the state which made a sensor touch in a finger.
When Coarse:250-> makes 130 decrease an LED electric current in scale100, it's increased in DC,AC.
Is this right movement?

When scale is 10, the reaction which is assumption street linear seems to be obtained.

    Hello,

    A1. If you are getting that error message then you will need to update the firmware as described in the user manual that can be downloaded from the eval board page on the website where you downloaded the wavetool download.

    A2. Please refer to the datasheet spec table to see what the resolution of the device is in nA/LSB per pulse for different TIA gain settings and LED pulse widths. Then you will be able to calculate how much input current is present at the input of the device based on the output codes for any number of pulses, TIA gain settings, and LED pulse widths of 2us or 3us which are the recommended pulse widths for the ADPD1081.

    A3. I don't understand your question.

    Regards,

    Kevin
