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.
Offset nulled.
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).
No external capacitor on REF.
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.

Typical Operating Characteristics

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

mea-
surement 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
