APPLICATION INFORMATION
The THS6226 class H line driver provides exceptional ac performance in conjunction with wide output voltage
swing. The class H operation allows voltage swings to exceed the power supply for short intervals limited only by
the charge in the capacitor. In class AB mode, the THS6226 is capable of driving a 60
Ω load from +1.9V to
+10.1V. In class H mode, under the same conditions, the output voltage range becomes an impressive
–5.5V to
+17.5V, or 46VPP differentially with the capacitor fully charged.
Figure 20 shows a fully-differential, noninverting amplifier configuration with active impedance. In this
configuration, the 10.2
Ω matching resistance appears through the transformer as 100Ω, minimizing reflection on
the line, while also minimizing transmission losses. The THS6226 gain is fixed and equal to 19V/V from input of
the amplifier to the output of the amplifier (INCD to OUTCD), not including the transformer-turn ratio.
To simplify the implementation as well as provide design flexibility, the THS6226 contains an integrated
mid-supply buffer that provides the correct biasing to the amplifier core without requiring any external
components. Also present is a two-pin serial interface that provides exceptional design flexibility and allows
minimal power consumption for each xDSL profile.
