8.2.1 Broadband PLC Line Driving

The THS6222 provides the exceptional ac performance of a wideband current-feedback op amp with a highly linear, high-power output stage. The low output headroom requirement and high output current drive capability makes the THS6222 an excellent choice for 12 V PLC applications. The primary advantage of a current-feedback op amp such as the THS6222 over a voltage-feedback op amp is that the ac performance (bandwidth and distortion) is relatively independent of signal gain. Figure 8-1 shows a typical ac-coupled broadband PLC application circuit where a current-output digital-to-analog converter (DAC) of the PLC application-specific integrated circuit (ASIC) drives the inputs of the THS6222. Though Figure 8-1 shows the THS6222 interfacing with a current-output DAC, the THS6222 can just as easily be interfaced with a voltage-output DAC by using much larger terminating resistors, RT1 and RT2.
