The OPA2674 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 OPA2674 consumes a low 9mA/ch quiescent current to deliver a very high 500mA output current. This output current supports even the most demanding ADSL CPE requirements with > 380mA minimum output current (+25°C minimum value) with low harmonic distortion. Differential driver applications deliver < –85dBc distortion at the peak upstream power levels of full rate ADSL. The high 200MHz bandwidth also supports the most demanding VDSL line driver requirements.

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.

Specified on ±6V supplies (to support +12V operation), the OPA2674 will also support a single +5V or dual ±5V supply. Video applications will benefit from a very high output current to drive up to 10 parallel video loads (15Ω) with < 0.1%/0.1° dG/dP nonlinearity.
