One Input Impedance got lower than other Input ports

Category: Hardware
Product Number: DG508AAZ/883B, DG508A

Dear Tech Support Team,

Hope you are doing well.

My board had got malfunction and I checked my board. I found that one input impedance in DG508AAZ/883B(8 Channel Input Multiplexer) was lower than other 7 input ports.

(Malfunction Input : About 10kohm / Normal Input : About 10Mohm)

This input was connected with output of OpAmp supplied with ±15V Voltage.

Could you let me know how it can happened?

I hope you to give me your opinion whether single product defect or damaged from other things.

I'm looking forward to your reply.

Thanks in advance.

Your sincerely,
