Hi, I'm working to design with the ADC08060. The datasheet seems to have conflicting information regarding the input voltage range.
If I set V_RT and V_RB appropriately according to the specification for min, max individually and min, max on the deltas between them as shown in page 5 of the datasheet, I'm wondering what happens if I feed an input voltage that is greater than or less than V_RT and V_RB respectively. There seems to be conflicting information on this.
In "Operating Ranges", there is mention that the input voltage range is valid from V_RB to V_RT. I'm not sure if this refers to the range at which the conversion is not clipped.
In note (2) on the Converter Electrical Characteristics on page 5, it mentions that "errors in the A/D conversion can occur if the input goes above DR VD or below GND by more than 100 mV", which makes sense (though why it mentions DR V_D instead of V_A is kinda puzzling". The example that follows is kind of weird though: "For example, if VA is 2.7VDC the full-scale input voltage must be ≤2.6VDC to ensure accurate conversions. " I'm not sure how that works out. This part seems like there are multiple typos, because the logical flow doesn't seem to work out.
In "Functional Description", it mentions that "Input voltages below VRB will cause the output word to consist of all zeroes. Input voltages above VRB will cause the output word to consist of all ones", which seems to indicate that voltage inputs beyond the reference voltages (up to a certain limit near the rails of course) is tolerable.
Please let me know of any clarifications regarding this situation, thanks!
