Function
1 3
Enables the stand-alone mode SDI to route to the DAC8531 D
IN
pin.
W2
1 3
Enables the user interface SDI to route to the DAC8531 D
IN
pin
1 3
Enables the stand-alone mode SCLK to route to the DAC8531 SCLK pin.
W3
1 3
Enables the user interface SCLK to route to the DAC8531 SCLK pin.
1 3
Enables the stand-alone mode FS to route to the DAC8531 SYNC pin.
W4
1 3
Enables the user interface FS to route to the DAC8531 SYNC pin.
1 3
Generates a SYNC signal for stand-alone mode after 24 SCLK cycles (default
mode).
W5
1 3
Generates a SYNC signal for stand-alone mode after 16 SCLK cycles (used only for
12-bit DACs described in table 1–1).
1 3
Provides 24-bit serial data for stand-alone mode when DAC8531 or DAC8501 is
installed in the EVM.
W6
1 3
Provides 16-bit serial data for stand-alone mode when DAC7512 or DAC7513 is
installed in the EVM.
1 3
Supplies V
CCA
to the positive rail of U12.
W7
1 3
Supplies a constant 5 V to the positive rail of U12 provided W12 is closed.
1 3
Ties the negative rail of U12 to AGND.
W8
1 3
Supplies a constant –5 V to the negative rail of U12 provided W12 is closed and a
±15 V supply is applied to the EVM board through J1 terminal.
1 3
EVM board is powered by a 3.3-V supply from the DSP through a common connector
if a DSK is used. Read caution in Section 1.2.1 when setting jumper.
W9
1 3
EVM board is powered by a 5-V supply from the DSP through a common connector if
a DSK is used. Read caution in Section 1.2.1 when setting jumper.
Legend: Indicates the corresponding pins that are shorted or closed.
