W1
13
V
REF(L)
tied to AGND
W1
13
Enables V
REF(L)
to be supplied by an external source of reference voltage
through TP1
W2
13
Enables the onboard adjustable reference to supply voltage for V
REF(H)
W2
13
Enables V
REF(H)
to be supplied by an external source of reference voltage
through TP2
W3
13
Negative supply rail of op amp, U2, is -15 V for bipolar application
W3
13
Negative supply rail of op amp, U2, is tied to AGND for unipolar application
W4
13
Positive supply rail of op amp, U2, is 15 V.
W4

Positive supply rail of op amp, U2, is V
CC
.
264
153
Routes the raw output of the DAC8531 to J4-2 and J5 output terminals
W5
264
153
Routes the output of U2 to J4-2 and 51 output terminals. Used for unipolar
and bipolar modes of operation.
264
153
Routes the output of U2 to J4-2 and J5 output terminals. Used for capacitive
load driving.
Disconnects V
REF(H)
from the negative input terminal of U2
W6
Allows V
REF(H)
to be routed to the negative input terminal of U2 for bipolar
operation
W7
Disconnects the negative terminal of U2 to AGND and disables 2×gain
W7
Configures U2 for a 2×gain output in unipolar mode
W8
Separate AGND and DGND from EVM board
W8
Connect AGND and DGND of EVM board
