Routes the adjustable, onboard +5-V reference or the fixed +4-V reference to the V
REF
input of the
DAC8560.
This is the default jumper position for DAC8560EVM because the +2.5-V internal reference is enabled
W4
by default.
Routes the user-supplied reference from TP1 or J4-20 to the V
REF
input of the DAC8560.
Negative supply rail of the output operational amplifier, U2, is powered by V
SS
for bipolar operation.
W5
Negative supply rail of the output operational amplifier, U2, is tied to AGND for unipolar operation.
CS signal from J2-1 is routed to drive the SYNC signal of the DAC8560.
W6
FSX signal from J2-7 is routed to drive the SYNC signal of the DAC8560.
