DESCRIPTION
The THS6132 is a Class-G current feedback differential
line driver ideal for full rate ADSL DMT systems. Its
extremely low power consumption of 600 mW or lower is
ideal for ADSL systems that must achieve high densities
in ADSL central office rack applications. The unique patent
pending architecture of the THS6132 allows the quiescent
current to be much lower than existing line drivers while
still achieving very high linearity. In addition, the multiple
bias settings of the amplifiers allow for even lower power
consumption for line lengths where the full performance of
the amplifier is not required. The output voltage swing has
been vastly improved over first generation Glass-G
amplifiers and allows the use of lower power supply
voltages that help conserve power. For maximum
flexibility, the THS6132 can be configured in classical
Class-AB mode requiring only as few as one power supply.

(1) 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.

(1) 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.
(2) VCC(H) must always be greater than or equal to VCC(L) for proper operation. Class-AB mode operation occurs when VCC(H) is equal to VCC(L)
and is considered acceptable operation for the THS6132 even though it is not fully specified in this mode of operation.
(3) The THS6132 incorporates 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 that could permanently damage
the device. See TI Technical Brief SLMA002 for more information about utilizing the PowerPAD thermally enhanced package.
