Problems with 24 bit ADC in EMI environments

[bbkv_tom]

24 Bit ADC used in my circuit is behaving erratically in EMI environment..have provided line inductors for all the I/O lines..what should be done for making it PASS for EFT,Fast transient bursts for ±2KV, on I/O lines, RS232, RS485 etc

put series resistors between ADC and rest of the circuit, make sure snubber networks are selecteted propertly in your switching power supplies
