BIT <7:0>

Analog Offset control continued (least significant bits of 9-bit word)

All 9-bits in this adjustment in address 0x03 and 0x04 set to 0 0000 0000 = –30 mV

All 9-bits in this adjustment in address 0x03 and 0x04 set to 1 1111 1111 = 30 mV

Step adjustment resolution is 120uV (or 1/4 LSB). Adjustments can be used for

calibration of analog signal path offset (for instance offset error induced outside of

the ADC) or to match multiple ADC offsets.

The default setting for this register is factory set to provide ~0 mV of ADC offset in

the output codes and is unique for each device.

Performance of the ADC is not specified across the entire offset control range.

Some performance degradation is expected as larger offsets are programmed.
