DESCRIPTION
The OPA2674 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 OPA2674 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擄C minimum value) with low harmonic distortion.
Differential driver applications deliver < 鈭?5dBc distortion
at the peak upstream power levels of full rate ADSL. The
high 200MHz bandwidth also supports 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
鹵6V
supplies (to support +12V operation), the
OPA2674 will also support a single +5V or dual
鹵5V
supply. Video applications will benefit from a very high
output current to drive up to 10 parallel video loads (15鈩?
with < 0.1%/0.1擄 dG/dP nonlinearity.
