OPA2674I-14DR

双宽带，具有电流限制高输出电流运算放大器 Dual Wideband, High Output Current Operational Amplifier with Current Limit

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.
