AD7760 diff amp AAF corner frequency/component values

Question asked by MPU on May 31, 2016

Hello,

 

Following the responses to this post - I am wondering whether/how lowering the corner frequency of the AAF prescribed in the AD7760 datasheet (Figure 50/Table 8) by increasing the value of the feedback capacitor would affect the overall accuracy of the A/D? Would it be recommended to use another stage if a lower corner frequency were needed?

 

Thank you!
