Shielding Temperature sensors connected to the LTC2983

Hi,

sensor shields

The LTC2983 datasheet has no information about shielding the Temperature sensors connected to its Analog Inputs.

  1. Where should the shields of the individual sensors be connected for obtaining best performance from the part? to GND or Earth?
  2. The system power supply has Y type capacitors between GND and Earth. Is it recommended to connect Y capacitors on the LTC2983 PCB between GND and Earth? X2Y capacitors between individual channels of the LTC2983 and GND? or Earth?
  3. What care is necessary to protect the part against ESD?

 

Thanks,

JayantD
