DESCRIPTION
The OPA2677 provides the high output current and low distortion
required in emerging ADSL and HDSL2 driver applications.
Operating on a single +12V supply, the OPA2677 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 mini-
mum output current 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 demanding VDSL line
driver requirements.

Power control features are included in the SO-14 package version
to allow system power to be minimized. Two logic control lines
allow four quiescent power settings. These include full power,
power cutback for short loops, idle state for no signal transmission
but line match maintenance, and shutdown for power off with a
high impedance output.
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/dØ non-linearity.
