The reference input voltage range may be restricted by the input voltage range requirement on the V
Temperature range is as follows: A Version = – 40∞C to +85∞C; S Version = –55∞C to +125∞C. See also Note 16.
Applies after calibration at the temperature of interest.
Positive full-scale error applies to both unipolar and bipolar input ranges.
These errors will be of the order of the output noise of the part, as shown in Table I, after system calibration. These errors will be 20 mV typical after self-calibration
Recalibration at any temperature or use of the background calibration mode will remove these drift errors.
These numbers are guaranteed by design and/or characterization.
This common-mode voltage range is allowed, provided the input voltage on AIN(+) and AIN(–) does not exceed AV
The analog inputs present a very high impedance dynamic load that varies with clock frequency and input sample rate. The maximum recommended source resis-
