AD7124-4 AD7124-8 ESD on current output pins

Hi,

 

Is there a recommended ESD protection circuit for the current output pins on the AD7124-8?  I am using AIN0 and AIN1 to source 500uA of current to measure a 3 wire RTD.  Since these pins are directly wired off the chip and out of the board they will get hit with ESD strikes during CE testing any by our customers.  How do I prevent damage to the IC?
