Power On POP noise in AD8397ARDZ

Hi,

 

We are using AD8397ARDZ for audio application and we are giving +/- 12V as supply. During power on I am able hear POP noise in the OPAMP output, When observed in the Oscilloscope I found few pulses in the output. I am sure that this POPs are not generated from DAC output since I have isolated the input to AD8397ARDZ and I have grounded them for testing purpose. Even During power down I am hearing same POP noise. Is there any way to reduce the power on POP noise??

 

Thanks and Regards,

Dinesh
