Texas Instruments OPA2675 Current Feedback Amplifier provides the low distortion and high output current required for power-line modem driver and test and measurement applications. The OPA2675 operates on power supplies ranging from 4.5V to 13V. The device consumes a low 16.5mA/channel quiescent current to deliver a very high 1000mA output current. The OPA2675 can support the most demanding power-line modem requirements with 850mA 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 Texas Instruments OPA2675 can be configured as a differential-input to differential-output, high current line driver, or used independently as individual op amps.
