This link connects AGNDA to 0 V.
This link selects the reference source:
This link selects the digital supply voltage value for the AD5764, U7, U8, and U9:
This link connects AGNDB to 0 V.
This link connects AGNDC to 0 V.
This link connects AGNDD to 0 V.
Function
This link selects the 5 V power supply source for the digital circuitry:
• Position A selects the USB port as the 5 V digital circuitry power supply source.
• Position B selects J2 as the 5 V digital circuitry power supply source.
This link selects the value of the short-circuit protection for the four DAC outputs:
• Position A selects a resistor value of 120 kΩ, selecting a current value of 500 μA.
• Position B selects a resistor value of 24 kΩ, selecting a current value of 2.5 mA.
• Position C selects a resistor value of 6 kΩ, selecting a current value of 10 mA.
• Position D selects a user-defined resistor value, selecting a user-defined current value.
•
•
This link connects the selected reference source to REFAB and REFCD: If sourcing REFAB external to the board via J3, Position B
should not be inserted. If sourcing REFCD external to the board via J4, Position A should not be inserted.

•
This link connects the TEMP pin to the input of the on-board ADC (AD5764R):
•
•
•
•
This link selects the state of the LDAC pin:
•
•
This link selects the state of the BIN/2sCOMP pin when external control is selected via LK11:
•
•
•
This link selects the state of the CLR pin when external control is selected via LK11:
•
•
This link selects whether the AD5764 evaluation board is controlled by the PC via the USB port or by an external source via
J21 or the SMB connectors:
•
•
Position A selects the internal reference as the reference source. (AD5764R)
Position B selects the on-board 5 V reference as the reference source.
Position A connects REFCD to the selected on-board or internal reference source.
Position B connects REFAB to the selected on-board or internal reference source.
When inserted, the voltage at the TEMP pin can be readback to the PC.
When removed, the voltage at the TEMP pin is disconnected from the on-board ADC input.
Position A selects +3.3 V as the supply value.
Position B selects +5 V as the supply value.
Position A allows the LDAC pin to be driven from either the PC or via J21 or the SMB connectors.
Position B connects the LDAC pin to DGND.
Position A connects the BIN/2sCOMP pin to DV
Position B connects the BIN/2sCOMP pin to DGND selecting twos complement as the data coding format
Removing LK9 allows the BIN/2sCOMP pin to be driven from J21.
When inserted, the CLR pin is connected to DGND and the four DAC outputs are cleared.
When removed, the CLR pin is pulled to DV
Position A selects the evaluation board to be controlled by an external source via J21 or the SMB connectors.
Position B selects the evaluation board to be controlled by the PC via the USB port.
