Temperature range: 40°C to +105°C.
2
Specification is not production tested, but is supported by characterization data at initial product release.
3
FS[9:0] is the decimal equivalent of Bit FS9 to Bit FS0 in the mode register.
4
Following a system or internal zero-scale calibration, the offset error is in the order of the noise for the programmed gain and output data rate selected. A system
full-scale calibration reduces the gain error to the order of the noise for the programmed gain and output data rate.
5
The analog inputs are configured for differential mode.
6
REJ60 is a bit in the mode register. When the first notch of the sinc filter is at 50 Hz, a notch is placed at 60 Hz when REJ60 is set to 1. This gives simultaneous
50 Hz/60 Hz rejection.
7
Digital inputs equal to DVDD or DGND.
