FLAH/EE MEMORY RELIABILITY CHARACTERISTICS
Temperature Range for ADuC847BS (MQFP package) is –40°C to +125°C.
These numbers are not production tested but are guaranteed by design and/or characterization data on production release.
The ADC is factory calibrated at 25°C with AVDD = DVDD = 5 V yielding this full-scale error of 10 µV. If user power supply or temperature conditions are
Gain Error Drift is a span drift. To calculate Full-Scale Error Drift, add the Offset Error Drift to the Gain Error Drift times the full-scale input.
In general terms, the bipolar input voltage range to the ADC is given by RangeADC = ±(VREF 2
1.25 V is used as the reference voltage to the ADC when internal VREF is selected via the XREF0 and XREF 1 bits in ADC0CON2.
The ADuC847BCP (CSP Package) has been qualified and tested with the base of the CSP Package floating.
Pins configured in SPI Mode, pins configured as digital inputs during this test.

Temperature Range for ADuC847BCP (CSP package) is –40°C to +85°C.
System Zero-Scale Calibration can remove this error.
significantly different from these, an Internal Full-Scale Calibration will restore this error to 10 µV. A system zero-scale and full-scale calibration will remove
this error altogether.
VREF = REFIN(+) to REFIN(–) voltage and VREF = 1.25 V when internal ADC VREF is selected.
RN = decimal equivalent of RN2, RN1, RN0
e.g., VREF = 2.5 V and RN2, RN1, RN0 = 1, 1, 0 the RangeADC = ±1.28 V, In unipolar mode, the effective range is 0 V to 1.28 V in our example.
