Function
Disconnects V
REF
from the negative input terminal of U12.
W10
Allows V
REF
to be routed to the negative input terminal of U12 for bipolar operation.
Disconnect the negative terminal of U12 to AGND.
W11
Allow a 2× gain output in unipolar mode.
Disconnects 12-V supply to U15 or R22 and R23 voltage divider circuit.
W12
Connects 12-V supply to U15 or R22 and R23 voltage divider circuit.

REF
pin.
Legend: Indicates the corresponding pins that are shorted or closed.
3.4 I/O Signal Mapping
Figure 3–9 and Figure 3–10 shows the I/O signals with respect to their
connectors/headers.
3.4.1 Daughterboard Connector Signal Mapping
Figure 3–9 describes the essential signals from the DSK boards that are
brought out through the common connectors which mates with the
daughterboard connectors J6 and J7.
