DESCRIPTION

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.

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.
