AD8018ARZ

AD8018 is a line drive amplifier intended for use in single-supply (5V) xDSL modems where high-output current and low distortion is 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. This amplifier can drive 400mA of current into 10 ohms (differential) while maintaining -82dBc out-of-band SFDR. 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). Application includes xDSL USB, PCI, PCMCIA cards, consumer DSL modems, and twisted pair line driver.

• Rail-to-rail output voltage and high output current
• Low single-tone distortion
• Low noise, low-power operation
• Current feedback amplifiers, high speed
• Typical -3dB bandwidth is 50MHz (G=1, VOUT <lt/> 0.4V p-p, RL=5ohm)
