Can I extend the input range of AD7150   to 100pF as CN-0129

though AD7150 does not have  teh register settings for EXCB= inverse of EXCA as AD7745/AD7746 ?

(For example,  if the voltage of EXCA is set to 1/2 by resistor deivider,  is the input range of AD7150 extended to 2 times?)


If there is any problem, could you teach me your advice.


 Our customer has used AD7150  but he needs to extend to 100pF  input range  at the next.
