a. These specifications are not tested in the outgoing inspection, but specified based on the device character-
ization
b. Measurement condition: Current is injected into one pin of the DUT. Measurement of effect of this injected
current is measured at adjacent pin.
Caution:
The value given in table ^3-13 stands for the degration by injected current on an adja-
cent pin. Therefore, this value is added to the specification of A/D converters overall
error defined seperatly as the electrical specifications (5. ”Electrical Specification
: AD Converter” on page 47)
If there is an increase leakage current, based on the negative currents injected into
the pin adjacent to the converted channel, the effect on the A/D converters accuracy
depends on the external analog source impedance.
