analog ground to the AGND connector. Connect the
+3.3V digital voltage supply to the DVDD connector
and the digital ground to the DGND connector on the
EV kit. If the on-board input buffer circuitry is to be uti-
lized, connect the +7V power supply and -2V power
supply to the corresponding OP+ and the OP- pads.
Connect the ground terminals of the +7V power supply
and -2V power supply together at the AGND pad.
On-Board Input Buffers
When using the on-board input buffers, connect a
desired common-mode voltage to the CMx+ and CMx-
pads to set the common-mode voltages for AINxA and
AINxB input channels, respectively.
When making the measurements for the true-differential
signal, set the jumpers according to Table 2. Connect the
positive input signal to the AINxA_BNC connector, and
the negative input signal to the AINxB_BNC connector.
When measuring the single-ended signal, set the
jumpers according to Table 2. Depending on the set-
ting in the Input Selection in Unipolar Mode group
box of the EV kit software, connect the single-ended
signal to the appropriate BNC connector.
To create a differential signal from a single-ended sig-
nal using the input buffers, set the jumpers according
to Table 3. Connect the single-ended signal to the
AINxA_BNC connector.
Set the jumpers according to Table 4 to bypass the on-
board input buffers.
