EVM Operation
3.1
Factory Default Settings
The EVM board is set to its default configuration from factory as described in
to operate in
unipolar +2.5-V mode of operation.
shows the default jumper configuration as described in the
table for the DAC8560.
Table 1. Factory Default Jumper Settings
Jumper
Reference
Function
Position
W1
1-2
Analog supply for the DAC8560 is +5 VA.
W2
1-2
DAC output (V
OUT
) is routed to J4-2.
V
REF
is not routed to the inverting input of the operational amplifier for voltage offset (for bipolar mode of
W3
OPEN
operation).
W4
OPEN
Onboard external buffered reference U3 or U4 is not routed to V
REF
.
W5
1-2
Negative supply rail of U2 operational amplifier is supplied with V
SS
.
W6
1-2
CS signal from J2 is used for frame synchronization, SYNC, signal.
For DAC8560EVM, the V
FB
is not routed out unless there is a need to minimize the output error. If using
W7
OPEN
W7, remove R1 and short W7, then connect V
FB
and V
OUT
as close as possible to the load.
Onboard external buffered reference U3 or U4 are not selected. Default is the +2.5-V internal reference of
W8
OPEN
the DAC8560.
W15
OPEN
Output operational amplifier, U2, is configured as voltage follower.
J4
1-2
DAC output (V
OUT
) is connected to the noninverting input of the output operational amplifier, U2.
