MODES OF OPERATION
SDP CONTROLLED MODE
The
AD7276
uses a high speed serial interface that allows
sampling rates of up to 3 MSPS. For more information about
the operation of the serial bus, refer to the
AD7276
data sheet.
The
EVAL-AD7276SDZ
communicates with the
EVAL-SDP-CB1Z
board using level shifters. The
EVAL-SDP-CB1Z
operates at a
3.3 V logic level, which allows logic voltages that exceed 3.3 V
to be used without damaging the SDP interface.
STANDALONE MODE
The
EVAL-AD7276SDZ
can also be used without the
EVAL-SDP-
CB1Z
controller board. In this case, the
EVAL-AD7276SDZ
is
connected to the digital interface using the SMB connectors as
described in Table 7.
