说明

The THS6032 is a low-power line driver ideal for asymmetrical digital subscriber line (ADSL) applications. This device contains two high-current, high-speed current-feedback drivers, which can be configured differentially for driving ADSL signals at the central office. The THS6032 features a unique class-G architecture to lower power consumption to 1.35 W. The THS6032 can also be operated in a traditional class-AB mode to reduce the number of power supplies to two.

The class-G architecture supplies current to the load from four supplies. For low output voltages (typically –2.5 < V_O < +2.5), some of the output current is supplied from the +V_CC(L) and –V_CC(L) supplies (typically ±5 V).
