I want to use an AD7124-8 ADC in a project:

http://www.analog.com/media/en/technical-documentation/data-sheets/AD7124-8.pdf ADC in a project:

I was wondering how to protect the analogue inputs from reverse polarity. According to the datasheet inputs can tolerate at most 0.05/0.1 volts of reverse voltage:

Maximum Tolerable Analogue Input Voltage

Thus, clamp diodes cannot offer any protection here. Any suggestions on how to resolve this issue?

P.S. Reverse voltage is at most 15 volts.

Thanks
