Note 1:
Relative accuracy is the deviation of the analog value at any code from its theoretical value after the gain and offset errors
have been calibrated.
Note 2:
Offset nulled.
Note 3:
In reference mode 00, the reference system powers up for each temperature measurement. In reference mode 01, the ref-
erence system powers up once per sequence of channels scanned. If a sample wait <80μs is programmed, the reference
system is on all the time. In reference mode 10, the reference system is on all the time (see Table 7).
Note 4:
No external capacitor on REF.
Note 5:
The operational input voltage range for each individual input of a differentially configured pair (AIN0
–
AIN7) is from GND to
V
DD
. The operational input voltage difference is from -VREF/2 to +VREF/2.
Note 6:
See Figure 3 and the Sampling Error vs. Input Source Impedance graph in the
Typical Operating Characteristics
section.

Note 9:
Performing eight single-ended external channels
’
temperature measurements, an internal temperature measurement, and
an internal V
DD
measurement with no sample wait results in a conversion rate of 2ksps per channel.
Note 10:
Performing eight single-ended voltage measurements, an internal temperature measurement, and an internal V
DD
measure-
ment with no sample wait results in a conversion rate of 7ksps per channel.
Note 11:
Performing eight single-ended voltage measurements, an internal temperature measurement, and an internal V
DD
measure-
ment with maximum sample wait results in a conversion rate of 3ksps per channel.
Note 12:
Defined as the shift in the code boundary as a result of supply voltage change. V

= min to max; full-scale input, mea-
sured using external reference.
