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. |
