PRELIMINARY TECHNICAL DATA
AD7621

PARALLEL INTERFACE
The AD7621 is configured to use the parallel interface
with either a 16-bit or 8-bit bus width. The data can be
read either after each conversion, which is during the
next acquisition phase, or during the following conversion
as shown, respectively, in Figure 15 and Figure 16. When
the data is read during the conversion, however, it is rec-
ommended that it is read only during the first half of the
conversion phase. That avoids any potential feedthrough
between voltage transients on the digital interface and the
most critical analog conversion circuitry.
