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 0016 to 0116 occurs ideally at the point of AN0 = 10 mV, but the

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 4916 is 23 mV, so the differential nonlinear error is represented

as “23 – 20 = 3 mV” (0.1 LSB).
