Multi-channel ADC for auto telemetry

Hello, I'm looking for a multi-channel (>=16) ADC with 0..16V inputs. The project is telemetry system for an old car with analog sensors. It seems that AD7616 (EVAL-AD7616) might fit but there is a little misunderstanding about it.

 

Manual says:

"The analog input range to the AD7616/AD7616-P is independently selectable with an absolute maximum input voltage range of ±16.5 V, which must not be exceeded. An input signal in the range of ±2.5 V, ±5 V, or ±10 V must be connected to the evaluation board via any of the analog input connecters."

 

So, is it OK for inputs to be ±16.5V? Maybe someone can recommend another solution?
