APPLICATION INFORMATION
BASIC OPERATION
The DAC8718 is a highly-integrated device with high-performance reference buffers and output buffers, greatly
reducing the printed circuit board (PCB) area and production cost. On-chip reference buffers eliminate the need
for a negative external reference. Figure 101 shows a basic application for the DAC8718.
