-40 TO +85擄C OPERATING RANGE
Two digital pins (PWDN0 and PWDN1) allow the driv-
er to work in full performance mode, in low-power
mode or two intermediate bias states.
The low-power mode biases the output stage in order
to provide a low impedance at the amplifier outputs
for back termination.
The STLC60133 is designed optimizing bandwidth
and distortion performances. For proper device oper-
ating it is necessary to work with a gain level greater
than 15.6dB.
Typical differential gain is normally +27dB, while typ-
ical common mode gain is 15.6dB
DESCRIPTION
The STLC60133 is a dual amplifier featuring a high
slew rate and a large bandwidth optimized for XDSL
applications. The device is available in a HTSSOP 28
pin package (4x9 mm) with an exposed leadframe.
Thanks to its small package this line driver is suitable
for high density ADSL line card.
