AD8391
xDSL Line Driver
3 V to 12 V with Power-Down
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-state
maintains low
amplifier output impedance), and Shutdown (Logic
0
places
amplifier outputs in a high impedance state). PWDN is refer-
enced to
V
S
.
Fabricated on ADI
s 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 Coastline

operates over the temperature range
