Note 1:
Tested at V
DD
= +3V, COM = GND, unipolar single-ended input mode.
Note 2:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after offset and gain errors have
been removed.
Note 3:
Offset nulled.
Note 4:
On channel is grounded; sine wave applied to off channels.
Note 5:
Conversion time is defined as the number of clock cycles times the clock period; clock has 50% duty cycle.
Note 6:
Input voltage range referenced to negative input. The absolute range for the analog inputs is from GND to V
DD
.
Note 7:
External load should not change during conversion for specified accuracy.
Note 8:
When bit 5 is set low for internal acquisition,
WR
must not return low until after the first falling clock edge of the conversion.
