- Page 5 PVDD/AVDD Supply The PVDD, the buck-boost converter supply, and AVDD, the analog supply, of the DAC8771 are connected to the same power net labeled PVDD/AVDD on the DAC8771EVM. Terminal block J3, shown Figure 3, allows for external voltage sources to be connected to the PVDD/AVDD supply. The PVDD/AVDD supply must be provided regardless of whether the buck-boost converter is in use or not.

- Page 7 JP11 in the 2-3 position and connect a supply voltage for the REF5050 to J6, as shown in Figure 5. To use an external reference voltage, remove JP11 and the reference can be connected to the DAC8771EVM through the center post of JP11. 2.5.3 VOUT, VSENSEP, and VSENSEN The VOUT pins can be accessed on terminal block J7, by the OUT test points.
- Page 8 Connecting the SM-USB-DIG To connect the EVM board and the SM-USB-DIG platform together, firmly slide the male and female ends of the 10-pin connectors together with the Texas Instruments logo of the SM-USB-DIG facing up as shown Figure 7. Make sure that the two connectors are completely pushed together as loose connections may cause intermittent operation.
