Dual, Wideband, High Output Current Amplifier and PLC Line Driver with Active Off-line Control

The OPA2673 provides the high output current and low distortion required for power-line modem driver and test and measurement applications. The OPA2673 operates on power-supplies ranging from 5.75 V to 13 V and consumes a low 16.5 mA/channel quiescent current to deliver a very high 700 mA output current. The OPA2673 supports the most demanding power-line modem requirements with an 460 mA specified minimum output current drive (at 25°C).

Power-control features are included to minimize system power consumption. Two logic-control lines allow for four quiescent power settings, full power, 75% bias power, 50% bias power, and offline mode with active offline control, to provide high impedance to large signals present at the output pin. The two channels of the OPA2673 can be used independently as individual op amps, or can be configured as a differential-input to differential-output, high-current line driver.
