ExtAdcOffset
- this parameter is the 2’s complement offset added to the scaled ADC measurement when the ADC refer-
ence is an external voltage.
ExtDacScaleFactor
- this parameter is the scale factor applied to a DAC measurement when the DAC reference is an ex-
ternal voltage. The scale factor parameter is multiplied by 32768. For example, the parameter value for a scale factor of
1.12 = 1.12 * 32768 = 36700.16 or 0x8F5C.
ExtDacOffset
- this parameter is 2’s complement the offset added to the scaled DAC measurement when the DAC refer-
ence is an external voltage.
VccAdcScaleFactor
- this parameter is the scale factor applied to an ADC measurement when the ADC reference is
Vcc/1.6. The scale factor parameter is multiplied by 32768. For example, the parameter value for a scale factor of 1.12 =
1.12 * 32768 = 36700.16 or 0x8F5C.
VccAdcOffset
- this parameter is the 2’s complement offset added to the scaled ADC measurement when the ADC refer-
ence is derived from Vcc/1.6.
VccDacScaleFactor
- this parameter is the scale factor applied to a DAC measurement when the DAC reference is Vcc.
The scale factor parameter is multiplied by 32768. For example, the parameter value for a scale factor of 1.12 = 1.12 *
32768 = 36700.16 or 0x8F5C.
VccDacOffset
- this parameter is the 2’s complement offset added to the scaled DAC measurement when the DAC refer-
ence is Vcc.
1VAdcScaleFactor
- this parameter is the scale factor applied to an ADC measurement when the ADC reference is the 1
V internal reference. The scale factor parameter is multiplied by 32768. For example, the parameter value for a scale fac-
tor of 1.12 = 1.12 * 32768 = 36700.16 or 0x8F5C.
1VAdcOffset
- this parameter is the 2’s complement offset added to the scaled ADC measurement when the ADC refer-
ence is the internal 1 V reference.
1VDacScaleFactor
- this parameter is the scale factor applied to a DAC measurement when the DAC reference is the in-
ternal 1 V reference. The scale factor parameter is multiplied by 32768. For example, the parameter value for a scale fac-
tor of 1.12 = 1.12 * 32768 = 36700.16 or 0x8F5C.
1VDacOffset
- this parameter is the 2’s complement offset added to the scaled DAC measurement when the DAC refer-
ence is the internal 1 V reference.
AdcDiffMode
- a parameter value of 0 selects single-ended ADC mode. In this mode, negative sensor inputs are connect-
ed to ground and positive sensor inputs to ADC0, ADC1 and ADC2 respectively. Three ADC measurements are made in
this mode with a range of 0x0000 to 0x07FF. A parameter value of 1 selects signed differential mode with gain. In this
mode, the negative sensor inputs are connected to ADC0 and the positive inputs are connected to ADC1 and ADC2. Two
ADC measurements are made in this mode, ADC1 to ADC0 and ADC2 to ADC0, with a range (signed) from 0xF800 to
0x07FF.
