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