NOTES: (1) In order to achieve the converter’s full-scale range, the input must be fully differential (AINN = 2 • REFIN – AINP). If the input is single-ended (AINN or
INP is fixed), then the full-scale range is one-half that of the differential range. (2) This range is set with external resistors and VBIAS (as described in the text).
A
Other ranges are possible. (3) Input impedance is higher with lower fXIN. (4) Applies after calibration. (5) After system calibration, these errors will be of the order
of the effective resolution of the converter. Refer to the Typical Performance Curves which apply to the desired mode of operation. (6) Recalibration can remove
these errors. (7) The specification also applies at fDATA /i, where i is 2, 3, 4, etc. (8) Voltages at the analog inputs must remain within AGND to AVDD. (9) The common-
mode rejection test is performed with 100mV differential input.

Instruments recommends that all integrated circuits be handled
with appropriate precautions. Failure to observe proper han-
dling and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
