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. Power control features are included in the SO-14 package version to allow syst...
