8.2.3.1 Design Requirements

The large output swing capability of the OPA690 and the high current capability allow the device to drive a 50-Ω line with a peak-to-peak signal up to 4 VPP at the load, or 8 VPP at the output of the amplifier using a single 12-V supply. Figure 8-9 shows such a circuit set for a gain of 8 to the output or 4 to the load.

The 5-pF capacitor in the feedback loop provides added bandwidth control for the signal path.
