AD7988-x: ADC input exceed Vref or GND

Can the ADC inputs of AD7988-1 or AD7988-5 exceed the reference voltage or go
below ground?


The ADC inputs should not exceed the reference or go below ground by more than
0.3V as this may result in the ADC being damaged. If this is a common
condition, then schottky diodes should be used to protect the inputs and limit
them to <0.3V.
