1 Specification is not production tested, but is supported by characterization data at initial product release.
2 Factory calibrated The absolute error includes factory gain calibration error, integral nonlinearity error, and offset error after system offset calibration, all at 25°C.
At different temperatures, compensation for gain drift over temperature is required.
3 The CAPDAC resolution is 7-bit in the actual CAPDAC full range. Using the on-chip offset calibration or adjusting the capacitive offset calibration register can further
reduce the CIN offset or the non-changing CIN component.
4 The VTCHOP bit in the VT SETUP register must be set to 1 for the specified temperature sensor and voltage input performance.
5 Full-scale error applies to both positive and negative full-scale.
