Product Description

Product Details
The AD8018 is a dual, high speed, low cost amplifier capable of driving low distortion signals to within 0.5 V of the supply rail. It is intended for use in single supply xDSL systems where low distortion and low cost is essential, and maximum reach on the line must be attained with the minimum of supply voltages. Each amplifier drives minimum 350 mA of output current and while maintaining -95 dBc of SFDR at 100 kHz, outstanding performance for any xDSL CPE application. The AD8018 is available with flexible standby and shutdown modes. Two bit control (1.5 V threshold referenced to DGND) will put the AD8018 into a full power standby (outputs low impedance) and shutdown (outputs high impedance).
Fabricated in ADI"s high speed XFCB process, the high bandwidth and fast slew rate of the AD8018 keep distortion to a minimum, while dissipating a minimum of power. The quiescent current of the AD8018 is low 9 mA/amplifier max. Low distortion, high output voltage drive, and high output current drive in small packages make the AD8018 ideal for use in low cost USB, PCMCIA and PCI Customer Premise Equipment for ADSL, SDSL, VDSL and proprietary xDSL systems.
An evaluation board is available for this product and may be ordered using the following product number AD8018ARU-EVAL.
