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.
