Link No. Function
LK13 This link selects the DAC voltage source.
Position A selects the AVDD analog circuitry power supply source.
Position B selects the on-board AD780 3 V reference as the power supply source.
LK14
This link allows the user to hardwire the ADDR1 pin to set the two LSBs (A1, A0) of the 7-bit address. 00011A1A0
(10-lead LFCSP); 001A3A2A1A0 (14-lead TSSOP).
Position A connects the pin to AVDD; therefore, two LSBs are 00.
Position B connects the pin to GND; therefore, two LSBs are 11.
No connection; therefore, two LSBs are 10.
LK15
This link allows the user to hardwire the ADDR2 pin to set the bits (A3, A2) of the 7- bit address. 001A3A2A1A0
(14-lead TSSOP only).
Position A connects the pin to AVDD; therefore, two bits are 00.
Position B connects the pin to GND; therefore, two bits are 11.
No connection; therefore, two bits are 10.
LK16
This link connects the OP_SEL pin of the AD780 reference to ground, selecting a 3 V output. Leaving no connect gives a
2.5 V output.
