Dual, High Output, Current-Feedback
OPERATIONAL AMPLIFIER
DESCRIPTION
The OPA2607 provides a high output voltage swing and low
distortion required for low turns ratio ADSL upstream driver
applications. Operating on a
±
12V supply, the OPA2607 con-
sumes a low 8.0mA/channel quiescent current to deliver a very
high 250mA peak output current. Guaranteed output current of
180mA supports even the most demanding ADSL CPE require-
ments with low harmonic distortion. Differential driver applica-
tions will deliver < –75dBc distortion at the peak upstream power
levels of full rate ADSL. Using a differential driver design, as
shown below, the OPA2607 can deliver a high 38Vp-p voltage
swing into a 1:0.8 step-down transformer to meet the ADSL CPE
upstream power requirements. This low turns ratio actually pro-
vides a step up to the much weaker downstream signal arriving on
the line side of this transformer, extending the DSL modem’s
reach.
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. An additional I
ADJ
pin allows the maxi-
mum supply current to be adjusted
±
25% from the nominal value.
Connecting this pin to +V
CC
will increase the full power quiescent
to 20mA, increasing the peak output current available, while
connecting this pin to –V
CC
will decrease the full power quiescent
to 12mA where a lower peak output current is required. The
digital control lines continue to scale the total quiescent current
from these new maximum levels in the same proportional steps as
before.
The OPA2607 is available in three package styles. For power
driver applications, a thermally enhanced
with a heat slug is available in both SO-8 and SO-14 pinouts. For
lower power receiver applications, a standard SO-8 package is
available.
