AD8016AREZ

AD8016 high output current dual amplifier is designed for the line drive interface in Digital Subscriber Line systems such as ADSL, HDSL2, and proprietary xDSL systems. The driver is capable, in full-bias operation, of providing 24.4dBm output power into low resistance loads, enough to power a 20.4dBm line, including hybrid insertion loss. 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 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.

• xDSL line driver that features full ADSL central office (CO), performance on ±12V supplies

• Large signal bandwidth is 90MHz (VOUT = 4V p-p, at 25°C, VS = ±12V, typ)
• Slew rate is 1000V/μs (typ, VOUT = 4V p-p, G = +2, at 25°C)
• Rise and fall time is 2ns (VOUT = 2V p-p, typ, at 25°C)
• Settling time is 23ns (0.1%, VOUT = 2V p-p, at 25°C)
• 28-lead TSSOP-EP package, temperature range from -40°C to +85°C
