DESCRIPTION
The STLC60133 is a dual amplifier featuring a high
slew rate and a large bandwidth optimized for XDSL
applications. The dev ice is avai lable in a HTSSOP 28
pin package (4x9 mm) with an exposed leadframe.
Thanks to its small pack age thi s l ine driv er is sui table
for high density ADSL line card.
HTSSOP28
ORDERING NUMBER: STLC60133
Temperature Range: -40°C to +85°C
Two digital pins (PWDN0 and PWDN1) allow the driver to work in full performance mode, in low-power
mode or two intermediate bias states.
The low-power mode biases the output stage in or der
to provide a low impedance at the amplifier outputs
for back termination.
The STLC60133 is designed optimizing bandwidth
and distortion perfor mances . For p roper devic e operating it is necessary to work with a gain level greater
than 15.6dB.
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.
PWDN1PWDN0Bias Level
11100%
1060%
0140%
0025% (low Zout but not OFF)
XXFull OFF (High Zout via 250uA pulled out of BIAS pin)

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 0
However, considering the internal parameter spread to full shutdown the STLC60133 is recommended to pull
down a 250
plifier 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 rai l. In thi s condi tion the BIA S pin can be used
as thermal overload indicator.
MAXIMUM POWER DISSIPATION
Maximum Junction Temperature allowed for proper device operation is Tj = 140°C. A Typical Thermal Resistance Junction to ambient of 29°C/W can be obtai ned mounting the devi ce 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 V
negative supply.
