(2) User adjustable Gain and Offset registers are provided for further error trim at VSGAIN and VSOFFSET, respectively. (3) Calculated and statistically projected worst case from characterization data. Includes inaccuracies due to IR reflow and thermal hysteresis over 3 cycles (25°C -> –40°C -> 25°C -> 105°C -> 25°C) (4) Computed from the first 500-hour operating life test at a stress temperature of 65°C. (5) Computed from the first 500-hour operating life test at a stress temperature of 105°C. (6) See Board Construction and Accuracy for board stack build information (1) Specified by design, not tested in production. (2) Calculated and statistically projected worst case from characterization data. Not tested in production. 6.14 ADC: AUXn General Purpose Inputs PARAMETER TEST CONDITIONS MIN TYP MAX UNIT VAUX_VR Input voltage range(1) VP/VDIG = 5.3 V 0 — 5 V VAUXERR65 Total AUX Channel Measurement Accuracy(2) VAUX = 0.05 V, 0°C ≤ TA ≤ 65°C –3 0.1 3 mV VAUX = 4.95 V, 0°C ≤ TA ≤ 65°C –10 0.1 10 mV VAUXERR105 Total AUX Channel Measurement Accuracy(2) VAUX = 0.05 V, –40°C ≤ TA ≤ 105°C –4.5 0.1 4.5 mV VAUX = 4.95 V, –40°C ≤ TA ≤ 105°C –12.5 0.1 12.5 mV |
