NOTES
13The AD7712 is tested with the following V
BIAS voltages. With AVDD = 5 V and VSS = 0 V, VBIAS = 2.5 V; with AVDD = 10 V and VSS = 0 V, VBIAS = 5 V and
with AVDD = 5 V and VSS = –5 V, VBIAS = 0 V.
14Guaranteed by design, not production tested.
15After 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.
16These calibration and span limits apply provided the absolute voltage on the AIN1 analog inputs does not exceed AV
DD + 30 mV or does not go more negative
than VSS – 30 mV.
17The offset calibration limit applies to both the unipolar zero point and the bipolar zero point.
