EVAL-AD7450A/EVAL-AD7451

MODES OF OPERATION

SERIAL INTERFACE

The AD7450A/AD7451 use a high speed serial interface which
allows sampling rates up to 1 MSPS. For details on the operation of
the serial bus, refer to the AD7450A
The EVAL-AD7450ASDZ/EVAL-AD7451SDZ
with the EVAL-SDP-CB1Z board using level shifters. The
EVAL-SDP-CB1Z operates at a 3.3 V logic level. This allows
VDRIVE voltages exceeding 3.3 V to be used without damaging
the SDP interface.
Details of the serial interface can be found in the
AD7451 data sheets.

STANDALONE MODE

The EVAL-AD7450ASDZ/EVAL-AD7451SDZ
used without the EVAL-SDP-CB1Z. In this case, connect to
the digital interface via the test-point connectors.
Remove R31, R35, and R36 to isolate the
from the SDP interface circuitry.
