A-D conversion standard characteristics
Fig. 59 A-D conversion standard characteristics
Figure 59 shows the A-D conversion standard characteristics.
The lower-side line on the graph indicates the absolute precision error. It represents the deviation from the ideal value.
For example, the conversion of output code from 00
measured value is –4 mV. Accordingly, the measured point of conversion is represented as “10 – 4 = 6 mV”.
The upper-side line on the graph indicates the width of input voltages equivalent to output codes. For example, the
measured width of the input voltage for output code 49
as “23 – 20 = 3 mV” (0.1 LSB).
