The OPA2675 provides the high output current and low distortion required for power-line modem driver and test and measurement applications. The OPA2675 operates on power-supplies ranging from 4.5 V to 13 V and consumes a low 16.5 mA/channel quiescent current to deliver a very high 1000 mA output current. The OPA2675 can support the most demanding power-line modem requirements with 850 mA assured 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 present a high impedance with large signals present at the output pin. The two channels of OPA2675 can be used independently as individual op amps or can be configured as a differential-input to differential-output, high current line driver.
