The OPA2677U is a dual SpeedPlus? wideband voltage-feedback Operational Amplifier for use with cable modem driver. The OPA2677 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 OPA2677 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 will deliver <-85dBc distortion at the peak upstream power levels of full rate ADSL. The high 200MHz bandwidth will also support the most demanding VDSL line driver requirements.
