AD8479 Distorted Output

Hi,

 

We are using AD8479 as shown in attached Fig. 1.
As a result, the output is distorted as attached Fig.2.
The phenomenon level is increased relative to the common mode voltage level.
And it is unchanged adding Rcomp as shown in the datasheet.
Can we use AD8479 in the following conditions?

 

Vs:±15V

Common mode voltage: ±4.24V to ±424V (AC 3V to AC 300V)
Signal frequency: 50Hz
Rshunt: 1Ω

 

 

 

 

Best regards,

 

Nikkee
