(Note 1)
(Note 3)
(Note 5)
Any input voltage below or greater than this voltage causes leakage current through the ESD diodes at the input pins.
This parameter is ensured by characterization and not 100% tested.
This input impedance is due to 3.2 pF internal input sampling capacitor.
The total conversion speed includes auto-calibration of offset and gain.
INL is the difference between the endpoints line and the measured code at the center of the quantization band.
Includes all errors from on-board PGA and V
Full Scale Range (FSR) = 2 x 2.048/PGA = 4.096/PGA.
This parameter is ensured by characterization and not 100% tested.
This parameter is ensured by design and not 100% tested.
