  • 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.
