The drivers are capable, in full-bias operation, of providing 24.4 dBm output power into low resistance loads, enough to power a 20.4 dBm line, including hybrid insertion loss. the xDSL hybrid in Figure 35 and Figure 36. Two digital bits (PWDN0, PWDN1) allow the driver to be capable of full performance, an output keep-alive state, or two intermediate bias states. The keep-alive state biases the output transistors enough to provide a low impedance at the amplifier outputs for back termination. The AD8016 is available in a low cost 24-lead SOIC_W_BAT and a 28-lead TSSOP_EP with an exposed lead frame (ePAD). Operating from ±12 V supplies, the AD8016 requires only 1.5 W of total power dissipation (refer to the Power Dissipation section for details) while driving 20.4 dBm of power downstream using The low power dissipation, high output current, high output voltage swing, flexible power-down, and robust thermal packaging enable the AD8016 to be used as the central office (CO) terminal driver in ADSL, HDSL2, VDSL, and proprietary xDSL systems.
