1. Does not include current consumption due to external loading on pins. No EEPROM access.
2. Sample mode current is specified during an A/D inactive cycle. Sample mode average current can be calculated using the formula: Average
3. Guaranteed by characterization or correlation to other test.
4. The max calibrated gain and offset errors are based on a 15-bit calibration procedure to generate the calibration factors. These calibration
5. Voltage is internal at A/D converter inputs. VSR is measured directly. VP and GPAD inputs are measured using internal level-translation circuitry
Sample Mode Supply Current = (IDDRUN + (n-1)*IDDINS)/Ns; where Ns is the programmed sample rate.
factors are then applied to correct the ADC results.
that scales the input voltage range appropriately for the converter.
