7.
Notes for A/D Conversion
The recommended external circuit impedance of analog inputs for MB90V520 is approximately 5 k
or less,
that for MB90F523B is approximately 15.5 k
or less, and that for MB90522A/523A/522B/523B is approximately
10 k
or less.
If using an external capacitor, the capacitance should be several thousand times the level of the chip’s internal
capacitor to allow for the partial potential between the external and internal capacitance.
If the impedance of the external circuit is too high, the analog voltage sampling interval may be too short. (for
sampling time
=
4
μ
s, machine clock frequency
=
16 MHz) .
