Adc_Disable; Adc_Read - Conrad C-Control Pro Mega Series Manual

131 C-Control Pro Mega Series
difference of one bit of the digitized measuring value corresponds to a voltage difference of 4mV, or:
u = x * 0,004V
Differential Inputs
ADC22x10
ADC23x10
ADC22x200
ADC23x200
ADC20x1
ADC21x1
ADC22x1
ADC23x1
ADC24x1
ADC25x1
ADC2 is the negative input.
The ADC can also perform differential measurements. The result can either be positive or negative.
The resolution during differential operation amounts to +/- 9 bit and is displayed in Two's
Complement format. For differential operation an amplifier with gains of V: x1, x10, x200 is available.
If x is a digital measuring value then the corresponding voltage value u is calculated as follows:
u = x * Reference Voltage / 512 / V
