1 Temperature range is –40°C to +85°C.
2 Specification is not production tested, but is supported by characterization data at initial product release.
3 Following a calibration, this error is in the order of the noise for the update rate selected.
4 Recalibration at any temperature removes these errors.
5 Full-scale error applies to both positive and negative full-scale and applies at the factory calibration conditions (AVDD = 4 V, TA = 25°C).
6 FS[3:0] are the four bits used in the mode register to select the output word rate.
7 Digital inputs equal to DVDD or GND.
