PRODUCT DESCRIPTION  
The AD8391 consists of two parallel, low cost xDSL line drive  
amplifiers capable of driving low distortion signals while running on  
both 3 V to 12 V single-supply or equivalent dual-supply rails. It is  
primarily intended for use in single-supply xDSL systems where low  
power is essential, such as line powered and battery backup systems.  
Each amplifier output drives more than 250 mA of current while  
maintaining 82 dBc of SFDR at 100 kHz on 12 V, outstanding  
performance for any xDSL CPE application.  
The AD8391 provides a flexible power-down feature consisting of  
a 1-pin digital control line. This allows biasing of the AD8391 to  
full power (Logic 1), Standby (Logic tri-statemaintains low  
amplifier output impedance), and Shutdown (Logic 0places  
amplifier outputs in a high impedance state). PWDN is refer-  
enced to VS.

Fabricated on ADIs high-speed XFCB process, the high bandwidth  
and fast slew rate of the AD8391 keep distortion to a minimum,  
while dissipating a minimum of power. The quiescent current of the  
AD8391 is low; 19 mA total static current draw. The AD8391  
comes in a compact 8-lead SOIC Thermal Coastlinepackage, and  
operates over the temperature range 40°C to +85°C.
