Product Summary
The OPA2677U/2K5 is an operational amplifier. It provides the high output current and low distortion required in emerging ADSL and HDSL2 driver applications. Operating on a single +12V supply, the OPA2677U/2K5 consumes a low 9mA/chan quiescent current to deliver a very high 500mA peak output current. Guaranteed output current supports even the most demanding ADSL CPE requirements with > 380mA minimum output current with low harmonic distortion. Differential driver applications of the OPA2677U/2K5 will deliver < –85dBc distortion at the peak upstream power levels of full rate ADSL. The high 200MHz bandwidth of the OPA2677U/2K5 will also support the most demanding VDSL line driver requirements. The applications of the OPA2677U/2K5 include xdsl line driver, cable modem driver, matched i/q channel amplifier, broadband video line driver, arb line driver and performance upgrade to AD8017.
