Factory Calibration
Devices that have been factory calibrated contain 30 bytes of calibration data in the Flash
option bit space. This data consists of 3 bytes for each input mode, one for offset and two
for gain correction. For a list of input modes for which calibration data exists, see
Calibration Data
User Calibration
If you have precision references available, its own external calibration can be performed
using any input modes. This calibration data takes into account buffer offset and non-lin-
earity, so it is recommended that this calibration be performed separately for each of the
ADC input modes planned for use.
Manual Offset Calibration
When uncalibrated, the ADC has significant offset (see
quently, manual offset calibration capability is built into the block. When the
trol Register 0
CALIBRATION mode, the differential inputs to the ADC are shorted together by an inter-
nal switch. Reading the ADC value at this point produces 0 in an ideal system. The value
actually read is the ADC offset. This value can be stored in non-volatile memory (see
Non-Volatile Data Storage
input offset error. There is no provision for manual gain calibration.
Software Compensation Procedure Using Factory Calibration Data
The value read from the ADC high and low byte registers is uncompensated. The user
mode software must apply gain and offset correction to this uncompensated value for
maximum accuracy. The following equation yields the compensated value:
where GAINCAL is the gain calibration value, OFFCAL is the offset calibration value and

plement format.
The offset compensation is performed first, followed by the gain compensation. One
bit of resolution is lost because of rounding on both the offset and gain computations.
As a result the ADC registers read back 13 bits: 1 sign bit, two calibration bits lost to
rounding and 10 data bits.
Also note that in the second term, the multiplication must be performed before the
