ADPD105 ADC offset setting

ADPD105 register 0x18~0x21 was the ADC offset register,default is 0x2000.

In general,how to setting this value?

  • Hello,

    When operating the device in normal mode, with zero input current, the device output will be at ~mid-scale. You can use the ADC offset registers to effectively "null" this offset. It's simply a digital subtraction of the ADC output minus the setting of the ADC offset register on a per pulse basis.
