The OPA2674IDG4 is a dual wideband Operational Amplifier with current limit. It provides the high output current and low distortion required in emerging xDSL and power line modem driver applications. Operating on a single +12V supply, the OPA2674 consumes a low 9mA/channel quiescent current to deliver a very high 500mA output current. This output current supports even the most demanding ADSL CPE requirements with >380mA minimum output current (+25°C minimum value) with low harmonic distortion. Differential driver applications deliver <-85dBc distortion at the peak upstream power levels of full rate ADSL. The high 200MHz bandwidth also supports the most demanding VDSL line driver requirements. Two logic control lines allow four quiescent power settings. These include full power, power cutback for short loops, idle state for no signal transmission but line match maintenance and shutdown for power off with a high impedance output.
