Section 22 A/D Converter
22.7.5
This LSI's analog input is designed so that the conversion accuracy is guaranteed for an input
signal for which the signal source impedance is 5 kΩ or less when EXCKS*
or 1 kΩ or less when EXCKS*
is provided to enable the A/D converter's sample-and-hold circuit input capacitance to be charged
within the sampling time; if the sensor output impedance exceeds the permissible signal source
impedance, charging may be insufficient and it may not be possible to guarantee the A/D
conversion accuracy. However, if a large capacitance is provided externally for conversion in
single mode, the input load will essentially comprise only the internal input resistance of 10 kΩ,
and the signal source impedance is ignored. However, since a low-pass filter effect is obtained in
this case, it may not be possible to follow an analog signal with a large differential coefficient
(e.g., 5 mV/μs or greater) (see figure 22.13). When converting a high-speed analog signal or
conversion in scan mode, a low-impedance buffer should be inserted.
