NOTES: (1) This range is set with external resistors and V
BIAS
(as described in the text). Other ranges are possible. (2) After the on-chip offset and gain
calibration functions have been employed. (3) Re-calibration can reduce these errors. (4) Input impedance changes with MCLK. (5) Assume brick wall digital
filter is used. (6) 20 Log (full scale/r ms noise). (7) After calibration, these errors will be of the order of the effective resolution.
