ADG1604 - Waveform change when connect input to source terminal

Question

Hello, 
 
 I'm using ADG1604 for channel selections. The input singal is sinwave, 50 Hz. 
 When I connect the input to the ADG1604 terminal, the signal waveform is changed alot. 
 1. My Schematic 
 
 2. The orginal input waveform 
 
 3. Input signal waveform when connected to the ADG1604

Please help me to findout the reason. 
 Thank you!

Hi, 
 This conversation has been taken offline. The cause of the issue has been identified and is because of the error in HW layout, not the ADG1604.
