FEATURES  
DESCRIPTION

•
WIDEBAND +12V OPERATION:  
420MHz (G = +5V/V)  
The OPA2670 provides the high output current and  
low distortion required in emerging xDSL and Power  
Line Modem driver applications. Operating on a  
single +12V supply, the OPA2670 consumes a low  
30.5mA quiescent current to deliver a very high  
700mA output current. This output current supports  
even the most demanding xDSL requirements with  
greater than 450mA minimum output current (+25°C  
minimum value) with low harmonic distortion.  
Differential driver applications deliver less than  
–71dBc distortion at the peak upstream power levels  
of full-rate ADSL. The high 420MHz bandwidth also  
supports the most demanding VDSL2 line driver  
requirements.  
•
HIGH OUTPUT CURRENT: 700mA  
•
OUTPUT VOLTAGE SWING: 9.4VPP into 10Ω  
Single-Ended Load  
•
•
•
HIGH DIFFERENTIAL SLEW RATE: 5000V/ms  
LOW SUPPLY CURRENT: 30.5mA  
FLEXIBLE POWER CONTROL  
APPLICATIONS

•
POWER LINE MODEM  
xDSL LINE DRIVERS  
CABLE MODEM DRIVERS  
BROADBAND VIDEO LINE DRIVERS  
ARB LINE DRIVERS  
Power control features are included to allow system  
power to be minimized. Two logic control lines allow  
four quiescent power settings, including full power,  
66% power, 33% power, and shutdown.
