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. Each amplifier can drive 400 mA of current into 10 (differential) while maintaining 82 dBc 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 ADI's 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 9 mA/amplifier. The AD8018 drive capability comes in compact 8-lead Thermal Coastline SOIC and 14-lead TSSOP packages. Low-distortion, rail-to-rail output voltage, and highcurrent 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. Both models will operate over the temperature range 40C to +85C.
