OPA2677U Datasheet

High Speed Operational Amplifiers


The OPA2677U 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 OPA2677U 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&deg;C minimum value) with low harmonic distortion. Differential driver applications will deliver < &ndash;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. OPA2677U Features &bull; WIDEBAND +12V OPERATION: 200MHz (G = +4)&bull; UNITY-GAIN STABLE: 220MHz (G = +1)&bull; HIGH OUTPUT CURRENT: 500mA&bull; OUTPUT VOLTAGE SWING: &plusmn;5V&bull; HIGH SLEW RATE: 1800V/&mu;s&bull; LOW SUPPLY CURRENT: 18mA&bull; FLEXIBLE SUPPLY RANGE: +5 to +12V Single Supply &plusmn;2.5 to &plusmn;6V Dual Supplies OPA2677U Applications &bull; xDSL LINE DRIVER&bull; CABLE MODEM DRIVER&bull; MATCHED I/Q CHANNEL AMPLIFIER&bull; BROADBAND VIDEO LINE DRIVER&bull; ARB LINE DRIVER&bull; POWER LINE MODEM&bull; HIGH CAP LOAD DRIVER
