PRODUCT DESCRIPTION  
The AD8019 is a low cost xDSL line driver optimized to drive a  
minimum of 13 dBm into a 100 Ω load while delivering outstand-  
ing distortion performance. The AD8019 is designed on a 24 V  
high-speed bipolar process enabling the use of 12 V power  
supplies or 12 V only. When operating from a single 12 V sup-  
ply the highly efficient amplifier architecture can typically deliver  
170 mA output current into low impedance loads through a  
1:2 turns ratio transformer. Hybrid designs using 12 V supplies  
enable the use of a 1:1 turns ratio transformer, minimizing attenu-  
ation of the receive signal. The AD8019 typically draws 9 mA/  
amplifier quiescent current. A 1-bit digital power down feature  
reduces the quiescent current to approximately 1.6 mA/amplifier.

Figure 1 shows typical Out of Band SFDR performance under  
ADSL CPE (upstream) conditions. SFDR is measured while  
driving a 13 dBm ADSL DMT signal into a 100 Ω line with  
50 Ω back termination.

Power into 200 Ω, Upstream  
The AD8019 comes in thermally enhanced 8-lead SOIC and  
14-lead TSSOP packages. The 8-lead SOIC is pin-compatible  
with the AD8017 12 V line driver.
