(1) The input impedance for PGA = 128 is the same as that for PGA = 64 (that is, 7MΩ/64).

(2) Calibration can minimize these errors.

(3) The gain self-calibration cannot have a REF IN+ of more than AVDD −1.5V with Buffer ON. To calibrate gain, turn Buffer OFF.

(4) ∆VOUT is change in digital result.
