PRODUCT DESCRIPTION
The AD8018 is intended for use in single-supply (5 V) xDSL modems where high-output current and low distortion are essential to achieve maximum reach. The dual high-speed amplifiers are capable of driving low distortion signals to within 0.5 V of the power supply rail.
   
FEATURES
    Ideal xDSL Line Drive Amplifier for USB, PCMCIA, or
        PCI-Based Customer Premise Equipment (CPE). The
        AD8018 provides maximum reach on 5 V supply,
        driving 16 dBm of power into a back-terminated,
        transformer-coupled 100 Ω while maintaining –82 dBc
        of out-of-band SFDR.
