(1) The input impedance for PGA = 128 is the same as that for PGA = 64 (that is, 7M/64).
(2) Calibration can minimize these errors.
(3) The gain 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.
(5) 9pF switched capacitor at fSAMP clock frequency (see Figure 14).
(6) Linearity calculated using a reduced code range of 512 to 65024; output unloaded.
(7) Ensured by design and characterization; not production tested.
(8) Analog Brownout Detect OFF (HCR1.3 = 1), Analog LVD OFF (LVDCON.7 = 1).
