FEATURES q WIDEBAND +12V OPERATION: 200MHz (G = +4) q UNITY-GAIN STABLE: 220MHz (G = +1) q HIGH OUTPUT CURRENT: 500mA q OUTPUT VOLTAGE SWING: ±5V q HIGH SLEW RATE: 1800V/ µs q LOW SUPPLY CURRENT: 18mA q FLEXIBLE SUPPLY RANGE: +5 to +12V Single Supply ±2.5 to ±6V Dual Supplies APPLICATIONS q xDSL LINE DRIVER q CABLE MODEM DRIVER q MATCHED I/Q CHANNEL AMPLIFIER q BROADBAND VIDEO LINE DRIVER q ARB LINE DRIVER q POWER LINE MODEM q HIGH CAP LOAD DRIVER DESCRIPTION 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 mini- mum 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 demand- ing 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 (15 Ω) 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.
