ADuC7033
overwrite the calibration coefficients or run ADC calibrations
to correct the gain error at the current PGA setting.
In summary, the simplified ADC transfer function can be
described as
This equation is valid for the voltage/temperature channel ADC.
For the current channel ADC,
where K is dependent on the PGA gain setting and ADC mode.
Normal Mode
For PGA gains of 1, 4, 8, 16, 32, and 64, the K factor is 1. For
PGA gains of 2 and 128, the K factor is 2. For a PGA gain of
256, the K factor is 4. For a PGA gain of 512, the K factor is 8.
Low Power Mode
The PGA gain is set to 128 and the K factor is 32.

Low Power Plus Mode
The PGA gain is set to 512 and the K factor is 8.
In low power and low power plus modes, the K factor doubles if
(REG_AVDD)/2 is used as the reference.
ADC DIAGNOSTICS
The ADuC7033 features diagnostic capability on both ADCs.
Current ADC Diagnostics
The ADuC7033 features the capability to detect open-circuit
conditions on the application board. This is accomplished using
the two current sources on IIN+ and IIN−; these are controlled
via ADC0CON[14:13].
Note that these current sources have a tolerance of ±30%. A
PGA gain ≥ 2 (ADC0CON[3:0] ≥ 0001) must be used when
current sources are enabled.
Temperature ADC Diagnostics
The ADuC7033 features the capability to detect open-circuit
conditions on the temperature channel inputs. This is
accomplished using the two current sources on VTEMP and
GND_SW, controlled via ADC1CON[14:13].
