The DM6441's analog video DAC outputs are designed to drive a 500-Ω load. Figure 7-54 describes a
typical circuit that will permit connecting the analog video output from the DM6441 device to standard
75-Ω impedance video systems. Another solution is to use a video amplifier, such as the Texas
Instruments' OPA361, which provides a complete solution to the typical output circuit shown in
Figure 7-54.
