OPA2677 - SpeedPlus™ Dual, Wideband, High Output Current Operational Amplifier

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/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 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.

Specified on ±6V supplies (to support +12V operation), the OPA2677 will also support a single +5V or dual ±5V supply. Video applications will benefit from its very high output current to drive up to 10 parallel video loads (15Ω) with < 0.1%/0.1° dG/dP nonlinearity.

The OPA2677 is available in either an SO-8 or QFN-16 and an HSOP-8 PowerPAD™ package.
