To carry out A/D conversion properly, charging the internal capacitor C shown in Figure 14.5.1 has to be
completed within a specified period of time. T (sampling time) as the specified time. Let output imped-
ance of sensor equivalent circuit be R0, microcomputer’s internal resistance be R, precision (error) of
the A/D converter be X, and the A/D converter’s resolution be Y (Y is 1024 in the 10-bit mode, and 256
in the 8-bit mode).
Figure 14.5.1 shows analog input pin and externalsensor equivalent circuit. When the difference be-
tween VIN and VC becomes 0.1LSB, we find impedance R0 when voltage between pins. VC changes
from 0 to VIN-(0.1/1024) VIN in timer T. (0.1/1024) means that A/D precision drop due to insufficient
capacitor chage is held to 0.1LSB at time of A/D conversion in the 10-bit mode. Actual error however is
the value of absolute precision added to 0.1LSB. When f(XIN) = 10MHz, T=0.3 s in the A/D conversion
mode with sample & hold. Output inpedance R0 for sufficiently charging capacitor C within time T is
determined as follows.
Thus, the allowable output impedance of the sensor circuit capable of thoroughly driving the A/D con-
verter turns out of be approximately 13.9k .

Hence,
