PERFORMANCE CHARACTERISTICS (CONT.)
Notes: 16. Specification is for the parameter over the specified temperature range and is for the device only. It does
not include the effects of external components.
17. Specification applies to the effective offset voltage calculated from the output codes of the digital filter
following offset calibration and correction.
18. Offset calibration is performed in the digital filter and includes the full-scale signal range.
