MODES OF OPERATION
SDP CONTROLLED MODE
The ADAQ7980 uses a high speed serial interface that allows
sampling rates of up to 1 MSPS. For more information about the
operation of the serial interface, refer to the
ADAQ7980 /
ADAQ7988 data sheet.
The ADAQ7980 uses the serial interface to transfer data to the
EVAL-SDP-CB1Z .
The EVAL-ADAQ7980SDZ communicates with the EVAL-SDP-
CB1Z board using a 3.3 V logic level. Logic voltages that exceed
3.3 V can damage the SDP interface.
USER DEFINED CONTROL MODE
The EVAL-ADAQ7980SDZ can also be used without the
EVAL-SDP-CB1Z controller board. In this case, the EVAL-
ADAQ7980SDZ connects to the serial interface using the P8
connector or the test points. For more information about the
operation of the serial interface, refer to the
ADAQ7980 / ADAQ7988 data sheet.
