description
The THS6092/3 is a high-speed line driver ideal for driving signals from the remote terminal to the central office
in asymmetrical digital subscriber line (ADSL) applications. It can operate from a single +12-V supply voltage
while drawing only 7.3 mA of supply current per channel. It offers low –72 dBc total harmonic distortion driving
a 25-Ω load (2 Vpp). The THS6092/3 offers a high 18.4-Vpp differential output swing across a 50-Ω load from
a single +12-V supply. The THS6093 features a low-power shutdown mode, consuming only 300 µA quiescent
current per channel. The THS6092/3 is packaged in a standard SOIC, SOIC PowerPAD, and TSSOP
PowerPAD package.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The THS6092 and THS6093 may incorporate a PowerPAD on the underside of the chip. This acts as a heatsink and must be
connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction
temperature which could permanently damage the device. See TI Technical Brief SLMA002 for more information about utilizing the
PowerPAD
thermally enhanced package.

Power rating is determined with a junction temperature of 130°C. This is the point where distortion starts to substantially increase. Thermal
management of the final PCB should strive to keep the junction temperature at or below 125°C for best performance.
