A/D converter programming (continued)
The total conversion time is compatible with the formula valid for ST10F269, while the
meaning of the bit fields ADCTC and ADSTC is no longer compatible: the minimum
conversion time is 388 TCL, which at 40MHz CPU frequency corresponds to 4.85
ST10F269).
A/D conversion accuracy
The A/D Converter compares the analog voltage sampled on the selected analog input
channel to its analog reference voltage (V
absolute accuracy of the A/D conversion is the deviation between the input analog value and
the output digital value. It includes the following errors:
●
●
●
●
These four error quantities are explained below using
Offset error
Offset error is the deviation between actual and ideal A/D conversion characteristics when
the digital output value changes from the minimum (zero voltage) 00 to 01
OFS).
Gain error
Gain error is the deviation between the actual and ideal A/D conversion characteristics when
the digital output value changes from the 3FE to the maximum 3FF, once offset error is
subtracted. Gain error combined with offset error represents the so-called full-scale error
(Figure
Quantization error
Quantization error is the intrinsic error of the A/D converter and is expressed as 1/2 LSB.
