Table 8. Jumper Setting Function (continued)
Reference Jumper Function
Setting
JMP4 Connects A0 (for DAC8164EVM) to IOV
DD
and sets the address pin, A0 of the DAC8164EVM to
high (A0 = 1). Also allows the host controller to control A0 pin via J2A-19.
Connects RST (for DAC8165EVM) to IOV
DD
and puts the DAC8165 to reset mode. Also allows the
host controller to control the RST pin of the DUT via J2A-19.
Connects A0 (for DAC8164EVM) to DGND and sets the address pin, A0 of the DAC8164EVM to low
(A0 = 0).
Connects RST (for DAC8165EVM) to DGND and puts the DAC8165 to reset mode.
JMP5 Disconnects the inverting input of the output operational amplifier, U2, from the gain resistor, R7 and
sets the output of the DAC for unipolar mode of operation.
Connects the inverting input of the output operational amplifier, U2, to the gain resistor, R7, for
bipolar mode of operation.
JMP6 Disconnects the inverting input of the output operational amplifier, U2, from the gain resistor, R9 and
configures the operational amplifier for unity gain.
Connects the inverting input of the output operational amplifier, U2, to the gain resistor, R9, and
configures the operational amplifier for 2x gain output.
JMP7 +5-V analog supply is selected for AV
DD
.
+3.3-V analog supply is selected for AV
DD
.
JMP8 This jumper position selects the adjustable +5V reference to route to the V
REF
H input of the
DAC8164/65.
This is the default jumper position for DAC8164/65EVM because the +2.5V internal reference is
enabled by default.
This jumper position selects the TP2 input terminal for reference to route to the V
REF
H input of the
DAC8164/65.
JMP9 This jumper position selects the AGND to route to the V
REF
L input of the DAC8164/65.
This jumper position selects the TP3 input terminal for reference to route to the V
REF
L input of the
DAC8164/65.
JMP10 Negative supply rail of the output operational amplifier, U2, is powered by V
SS
for bipolar operation.
Negative supply rail of the output operational amplifier, U2, is tied to AGND for unipolar operation.
JMP11 Routes V
OUT
to J4A-2.
Routes V
OUT
to J4A-10.
JMP12 Routes V
OUT
to J4-4.
Routes V
OUT
to J4-12.
