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 Ω (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).  
Low-Power Operation  
3.3 V to 8 V Power Supply Range  
Two Logic Bits for Standby and Shutdown  
Low Supply Current of 9 mA/Amplifier (Typ)  
Current Feedback Amplifiers  
High Speed  
130 MHz Bandwidth (–3 dB)  
300 V/␮s Slew Rate  
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.
