PRODUCT DESCRIPTION

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 three-state maintains low

amplifier output impedance), and shutdown (Logic 0 places

amplifier outputs in a high impedance state). PWDN is refer-

enced to –V

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” package and

operates over the temperature range –40°C to +85°C.

UPSTREAM POWER – 10dB/DIV

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.
