The AD7609 datasheet states in table 2 that the common-mode input range is
Min = -4V
Max = +4V
Typ = ±5V
which is obviously a wider range than the min/max range. What is the truth here?
Does using the full common-mode input range have impact on accuracy?
In Does the Vx- pin of AD7609 be 180° to Vx+ pin it is implied that exceeding the common-mode input range could damage the part. Is that really true?
