• WIDEBAND +12V OPERATION:

The OPA2673 provides the high output current and

low distortion required in emerging Power Line

Modem driver applications. Operating on a single

demanding Power Line Modem requirements with

• HIGH SLEW RATE: 3000V/µs

greater than 460mA minimum output current (+25°C

• LOW SUPPLY CURRENT: 16mA/ch

minimum value) with low harmonic distortion.

• OVERTEMPERATURE PROTECTION CIRCUIT

Power control features are included to allow system

control lines allow four quiescent power settings: full
