AC Electrical Characteristics
(Continued)
Note 7:
The CS input is assumed to bracket the WR strobe input and therefore timing is dependent on the WR pulse width. An arbitrarily wide pulse width will hold
the converter in a reset mode and the start of conversion is initiated by the low to high transition of the WR pulse (see timing diagrams).
Note 8:
None of these A/Ds requires a zero adjust (see section 2.5.1). To obtain zero code at other analog input voltages see section 2.5 and Figure 7
Note 9:
The V
/2 pin is the center point of a two-resistor divider connected from V
to ground. In all versions of the ADC0801, ADC0802, ADC0803, and
ADC0805, and in the ADC0804LCJ, each resistor is typically 16 k
. In all versions of the ADC0804 except the ADC0804LCJ, each resistor is typically 2.2 k
.
Note 10:
Human body model, 100 pF discharged through a 1.5 k
resistor.
