Parameters
DD
- = V
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.
