(1)
Calibration can minimize these errors.
(2)
The self-gain calibration cannot have a REF IN+ of more than
AVDD 1.5V with Buffer ON. To calibrate gain, turn Buffer OFF.
(3)
VOUT is change in digital result.
(4)
9pF switched capacitor at
fSAMP clock frequency (see Figure 14).
(5)
The input impedance for PGA = 128 is the same as that for PGA = 64 (that is, 7M
/64).
