The AD8018ARZ is a rail-to-rail current Line Drive Amplifier intended for use in single-supply xDSL modems where high-output current and low distortion are essential to achieve maximum reach. The dual high-speed amplifier is capable of driving low distortion signals to within 0.5V of the power supply rail. The amplifier can drive 400mA of current into 10R (differential) while maintaining -82dBc out-of-band SFDR. The AD8018 is available with flexible standby and shutdown modes. Two digital logic bits (PWDN1 and PWDN0) may be used to put the AD8018 into one of three modes - full power, standby (outputs low impedance) and shutdown (outputs high impedance). Fabricated with ADIs high-speed XFCB (eXtra Fast Complementary Bipolar) 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 a low 9mA/amplifier.
