NOTES
12
The AD7710 is tested with the following V
BIAS
voltages. With AV
DD
= +5 V and V
SS
= 0 V, V
BIAS
= +2.5 V; with AV
DD
= +10 V and V
SS
= 0 V, V
BIAS
= +5 V and
with AV
DD
= +5 V and V
SS
= –5 V, V
BIAS
= 0 V.
13
Guaranteed by design, not production tested.
14
After calibration, if the analog input exceeds positive full scale, the converter will output all 1s. If the analog input is less than negative full scale then the device will
output all 0s.
15
These calibration and span limits apply provided the absolute voltage on the analog inputs does not exceed AV
DD
+ 30 mV or go more negative than V
SS
– 30 mV.
The offset calibration limit applies to both the unipolar zero point and the bipolar zero point.
