It is intended for use in single supply xDSL systems where low distortion and low cost is essential. The amplifiers will be able to drive minimum 200mA of output current per amplifier. The AD8017 will deliver -68dBc of SFDR at 500kHz, 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 of power. The quiescent current of the AD8017 is low 7mA/amp max. 25 50 100 Rload (Ohms) 1000 10000 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 +12V 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 0°C to +85°C. REV. PrA 10/12/98 1 This information applies to a product under development.
