PRODUCT DESCRIPTION

The AD8017 is a low cost, dual high speed amplifier capable of

driving low distortion signals to within 1.0 V of the supply rail.

It is intended for use in single supply xDSL systems where low

distortion and low cost are essential. The amplifiers will be able

to drive a minimum of 200 mA of output current per amplifier.

The AD8017 will deliver –78 dBc of SFDR at 500 kHz, required

for many xDSL applications.

Fabricated in ADI’s high speed XFCB process, the high bandwidth

and fast slew rate of the AD8017 keep distortion to a minimum, while

dissipating a minimum amount of power. The quiescent current of

the AD8017 is 7 mA/amplifier.

Low distortion, high output voltage drive, and high output current

drive make the AD8017 ideal for use in low cost Customer Premise

End (CPE) equipment for ADSL, SDSL, VDSL and proprietary

xDSL systems.

The AD8017 drive capability comes in a very compact form.

Utilizing ADI’s proprietary Thermal Coastline SOIC package,

the AD8017’s total (static and dynamic) power on 12 V supplies

is easily dissipated without external heat sink, other than to place

the AD8017 on a 4-layer PCB.

The AD8017 will operate over the commercial temperature

range –40

°C to +85°C.
