PRODUCT DESCRIPTION
The AD8019 is a low cost xDSL line driver optimized to drive a
minimum of 13 dBm into a 100 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 line with
50 back termination.
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.
