DESCRIPON

The OPA2674 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/ch 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.
