Analog Devices Announces Driver Amplifier for xDSL Applications Where Low Distortion, High Speed Are Essential, and Low Cost is Critical High-Output Current, Low Cost, Small Package; High-Performance Line Driver Well-Suited for xDSL CPE Designs NORWOOD, Mass., Oct. 29 /PRNewswire/ -- Analog Devices announces the AD8017, a low-cost, dual, high-output current, low-power amplifier, capable of driving low-distortion signals to within 1.0 V of the +12-V supply rail. This driver amplifier was designed for single +12-V supply, xDSL systems such as PC-based ADSL, HDSL and xDSL modems. The AD8017 drives a minimum of 270 mA of output current per amplifier while maintaining -58 dBc SFDR (spurious free dynamic range) at 1 MHz into 10 ohms, setting the standard for useable output current drive. Fabricated on Analog Devices' high-speed XFCB process, the high-bandwidth (160 MHz -- 3 dB BW), fast slew rate (1500 V/microseconds) and low noise (1.9 nV/square root Hz) of the AD8017 keep distortion to a minimum while drawing a low quiescent current of just 7 mA/amplifier (typ). This combination of low distortion, high-output voltage drive and high- output current drive makes the AD8017 well-suited for low-cost Customer Premise End (CPE) equipment for ADSL, SDSL, VDSL and proprietary xDSL systems. The AD8017 is fully specified at +/-2.5-V and +/-6-V supplies and also operates from a +12-V supply. Utilizing ADI's proprietary ''Thermal Coastline'' thermally enhanced SOIC package, the AD8017's total power (static and dynamic) on +12-V supplies easily dissipates without an external heat sink (other than placing the AD8017 on a 4-layer PCB). Operating temperature range is from 0 to +85 degrees Celsius. This dual, high-output current drive amplifier is available now and sells for $2.78 in 1000-piece quantities.
