OPA2673 Dual Wideband High Output Current Operational Amplifier with Current Limit

The OPA2673 provides the high output current and low distortion required in emerging Power Line Modem driver applications. Operating on a single +12V supply, the OPA2673 consumes a low 16mA/ch quiescent current to deliver a very high 700mA output current. This output current supports even the most demanding Power Line Modem requirements with greater than 460mA minimum output current (+25°C minimum value) with low harmonic distortion.

Power control features are included to allow system power consumption to be minimized. Two logic control lines allow four quiescent power settings: full power, 75% bias power in applications that are less demanding, 50% bias power cutback for short loops, and offline with active offline control to present a high impedance even with large signals present at the output pin
