(1)See text for more information on input impedance.
(2)SPS = samples per second.
(3)FSR = full-scale range = 4VREF/PGA.
(4)fCM is the frequency of the common-mode input signal.
(5)Placing a notch of the digital filter at 60Hz (setting fDATA = 60SPS, 30SPS, 15SPS, 10SPS, 5SPS, or 2.5SPS) will further improve the
common-mode rejection of this frequency.
(6)The reference input range with Buffer on is restricted only if self-calibration or gain self-calibration is to be used. If using system calibration or
writing calibration values directly to the registers, the entire Buffer off range can be used.
