Full Rate ADSL Line Driver With Powerdown

The AD8016 is a 2nd generation DSL line driver capable of delivering full rate ADSL from the Central Office on a cool 1.5 W total power dissipation.

With the addition of a flexible Standby functionality, and packaged in a 20-Lead PSOP, a 24-Lead SOIC, and a 28-Lead TSSOP package, the AD8016 is optimized for DSL line driving at both ends of the line. Novel circuit design and a new ±12 V, high speed bipolar process enable each amplifier in the dual AD8016 to deliver 20 V pk-to-pk output voltage and more than 400 mA typical output current.

The combination of a breakthrough in two stage current gain and high speed bipolar process technology means that the AD8016 can deliver low distortion output voltages to within 2 V of the power supply rail, setting the standard in high efficiency.
