TUE is tested at V
Not subject to production test, verified by design/characterization
This represents an equivalent switched capacitance. This capacitance is not switched to the reference voltage
at once. Instead of this, smaller capacitances are successively switched to the reference voltage.
The sampling capacity of the conversion C-Network is pre-charged to V
the C-Network. Because of the parasitic elements, the voltage measured at ANx is lower than V
