Permissible Signal Source Impedance: H8S/2357 Group analog input is designed so that conversion precision is
guaranteed for an input signal for which the signal source impedance is 10 kohm or less. This specification 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 10 kohm, charging may be insufficient and it may not be possible to guarantee the A/D
conversion precision.
