1.0 Functional Description

OTHER INTERFACE CONSIDERATIONS
In order to maintain conversion accuracy, WR has a maxi-
mum width spec of 50 μs. When the MS flash ADC’s
sampled-data comparators (Section 1.2) are in comparison
mode (WR is low), the input capacitors (C, Figure 8 ) must
hold their charge. Switch leakage and inverter bias current
can cause errors if the comparator is left in this phase for too
long.
Since the MS flash ADC enters its zeroing phase at the end
of a conversion (Section 1.3), a new conversion cannot be
started until this phase is complete. The minimum spec for
this time (t
P
, Figures 2, 3, 4, 5 ) is 500 ns.
