Product Summary
The AD8018ARZ is a xDSL line drive amplifier. It 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. Each amplifier can drive 400 mA of current into 10 (differential) while maintaining –82 dBc out-of-band SFDR. The AD8018ARZ is available with flexible standby and shutdown modes. Two digital logic bits (PWDN1 and PWDN0) may be used to put the AD8018ARZ into one of three modes: full power, standby (outputs low impedance), and shutdown (outputs high impedance).The AD8018ARZ can be applied in xDSL USB, PCI, PCMCIA gards consumer DSL modems, twisted pair line driver.
