(1) See text for more information on input impedance.
(2) SPS = samples per second.
(3) FSR = full-scale range = 4V REF /PGA.
(4) f CM is the frequency of the common-mode input signal.
(5) Placing a notch of the digital filter at 60Hz (setting f DATA = 60SPS, 30SPS, 15SPS, 10SPS, 5SPS, or 2.5SPS) will further improve the
(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
common-mode rejection of this frequency.
writing calibration values directly to the registers, the entire Buffer off range can be used.
