DC Electrical Characteristics
Symbol
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions.
Note 2: All voltages are measured with respect to GND, unless otherwise specified. The separate A GND point should always be wired to the D GND.
Note 3: A zener diode exists, internally, from V
Note 4: For V
for analog input voltages one diode drop below ground or one diode drop greater than the V
level analog inputs (5V) can cause this input diode to conduct — especially at elevated temperatures, and cause errors for analog inputs near fullscale. The spec al-
lows 50 mV forward bias of either diode. This means that as long as the analog V
be correct. To achieve an absolute 0 V
tolerance and loading.
Note 5: With an asynchronous start pulse, up to 8 clock periods may be required before the internal clock phases are proper to start the conversion process. The
start request is internally latched, see Figure 3 .
Note 6: 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 7: All typical values are for T
Note 8: Accuracy is guaranteed at f
Note 9: The V
of these two equal resistors.
Note 10: Human body model, 100 pF discharged through a 1.5 k
