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. Each amplifier can drive 400 mA
of current into 10
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 Comple-
mentary Bipolar) process, the high bandwidth and fast slew rate
of the AD8018 keep distortion to a minimum, while dissipat-
ing 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 high-
current 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 –40 C to +85 C.
