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 (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.
