APPLICATIONS  
FEATURES  
● xDSL LINE DRIVER  
●
WIDEBAND +12V OPERATION: 200MHz (G = +4)  
● UNITY GAIN STABLE: 220MHz (G = 1)  
● HIGH OUTPUT CURRENT: 500mA  
● OUTPUT VOLTAGE SWING: ±5V  
● HIGH SLEW RATE: 1800V/µs  
● CABLE MODEM DRIVER  
● MATCHED I/Q CHANNEL AMPLIFIER  
● BROADBAND VIDEO LINE DRIVER  
● ARB LINE DRIVER  
● PERFORMANCE UPGRADE TO AD8017  
● LOW SUPPLY CURRENT: 18mA  
● FLEXIBLE POWER CONTROL  
Power control features are included in the SO-14 package version  
to allow system power to be minimized. Two logic control lines  
allow four quiescent power settings. These include full power,  
power cutback for short loops, idle state for no signal transmission  
but line match maintenance, and shutdown for power off with a  
high impedance output.  
DESCRIPTION  
The OPA2677 provides the high output current and low distortion  
required in emerging ADSL and HDSL2 driver applications.  
Operating on a single +12V supply, the OPA2677 consumes a  
low 9mA/chan quiescent current to deliver a very high 500mA  
peak output current. Guaranteed output current supports even the  
most demanding ADSL CPE requirements with > 380mA mini-  
mum output current with low harmonic distortion. Differential  
driver applications will deliver < –85dBc distortion at the peak  
upstream power levels of full rate ADSL. The high 200MHz  
bandwidth will also support the most demanding VDSL line  
driver requirements.  
Specified on ±6V supplies (to support +12V operation), the  
OPA2677 will also support a single +5V or dual ±5V supply.  
Video applications will benefit from its very high output  
current to drive up to 10 parallel video loads (15Ω) with < 0.1%/  
0.1° dG/dØ non-linearity.
