Description for the OPA2675
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 supports the most demanding power-line modem requirements with an 850 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 OPA2675 can be used independently as individual op amps, or can be configured as a differential-input to differential-output, high-current line driver.
