Notes:

7. The ADCs accept input voltages up to the analog supplies (VA+, VA-). They will produce a positive

full-scale output for inputs above 3.68 V and negative full-scale output for inputs below -3.68 V. These

values are subject to the gain error tolerance specification. Additional tag bits are output to indicate

the amount of overdrive.
