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.

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
