Two digital pins (PWDN0 and PWDN1) allow the driver to work in full performance mode, in low-power
mode or two intermediate bias states.
DESCRIPTION
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 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.
The STLC60133 is designed optimizing bandwidth
and distortion performances. For proper device operating it is necessary to work with a gain level greater
than 15.6dB.
Thanks to its small package this line driver is suitable
for high density ADSL line card.
Typical differential gain is normally +27dB, while typical common mode gain is 15.6dB

Power Down Management
The STLC60133 provides several quiescent bias levels from full performance, to reduced bias (in three steps
through PWDN0/1 pins) or to full OFF operation (through BIAS pin). According to the different XDSL application
(both site CO and CPE), different bias levels can be chosen maintaining good MTPR performances. In the following table are shown the bias levels versus the PWDN values.

STLC60133
The bias level is programmed by the TTL logic level applied to the PWDN pins. The DGND pin is the logic
ground reference for the PWDN pins. For normal operation the BIAS pin shall be left open.
The BIAS control pin can be used to adjust the internal biasing and thus the quiescent current. By pulling out a
current of 0µA to 200µA, the quiescent current can be adjusted from 100% (full ON) to a full OFF condition.
However, considering the internal parameter spread to full shutdown the STLC60133 is recommended to pull
down a 250µA current from the BIAS pin. In the following figure is shown an implementation of a complete amplifier shutdown. To partially reduce the internal biasing also the PWDN pins can be used.

THERMAL SHUTDOWN
A thermal protection is embedded in the STLC60133. In case of thermal overload the device is shut down at
160°C and returns to normal operation when the temperature becomes lower than 145°C.
During the thermal shutdown the voltage at the BIAS pin goes to the DGND rail; when the device returns to the
normal operation the voltage at the BIAS pin goes to the positive rail. In this condition the BIAS pin can be used
as thermal overload indicator.
MAXIMUM POWER DISSIPATION
Maximum Junction Temperature allowed for proper device operation is T j = 140°C. A Typical Thermal Resistance Junction to ambient of 29°C/W can be obtained mounting the device on a 4 layer board whithin 10 square
inches of copper and having the exposed pad contacting a proper copper area . It shall be noted that the exposed pad of the device is electrically connected to the VSS negative supply.
