The OPA2674 provides the high output current and low istortion required in emerging xDSL and Power Line odem driver applications. Operating on a single +12V upply, the OPA2674 consumes a low 9mA/ch quiescent urrent to deliver a very high 500mA output current. This utput current supports even the most demanding ADSL PE requirements with > 380mA minimum output current +25°C minimum value) with low harmonic distortion. ifferential driver applications deliver < −85dBc distortion t the peak upstream power levels of full rate ADSL. The igh 200MHz bandwidth also supports the most emanding VDSL line driver requirements.

Power control features are included in the SO-14 package ersion to allow system power to be minimized. Two logic ontrol lines allow four quiescent power settings. OPA2674 includes full power, power cutback for short loops, idle state or no signal transmission but line match maintenance, and shutdown for power off with a high impedance output. pecified on ±6V supplies (to support +12V operation), the PA2674 will also support a single +5V or dual ±5V supply. Video applications will benefit from a very high utput current to drive up to 10 parallel video loads (15) ith < 0.1%/0.1° dG/dP nonlinearity.
