Dual, Wideband, High Output Current Amplifier and PLC Line Driver with Active Off-line Control | RGV | 16 | -40 to 85

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.
