I have a question about AD7864BSZ-1REEL.
① In data sheet P1
"Selection Input Range: ± 10 V, ± 5 V for AD7864 - 1"
Although there is description, please tell me how to select the range
* Currently it is used in the ± 5 V range, but when using it in the ± 10 V range,
Is it possible to automatically determine whether to change with one pin setting?
② When using the input range with ± 5 V (FSR = 10 V), exceeding + 5 V
What will the output look like when analog input is entered?
※ There is such thing as overflow and minus output.
③ It is related to the above ②, but to the absolute maximum rating of Datasheet P5
"AD7864 - 1 (± 5 V Input Range) ... - 7 V to + 20 V"
Although it is described, input range is ± 5 V or -7 to +20 V,
Which is better understood?
