description
The THS414x is one in a family of fully differential
input/differential output devices fabricated using
Texas Instruments' state-of-the-art BiComI
complementary bipolar process.
The THS414x is made of a true fully-differential
signal path from input to output. This design leads
to an excellent common-mode noise rejection and
improved total harmonic distortion.

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 THS414x may incorporate a PowerPad
on the underside of the chip. This acts as a heatsink and must be connected to a thermally
dissipative 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 and SLMA004 for more information about utilizing the PowerPad
thermally enhanced package.
NOTE 2: The absolute maximum temperature under any condition is limited by the constraints of the silicon process.
NOTE 3: The maximum junction temperature for continuous operation is limited by package constraints. Operation above this temperature may
result in reduced reliability and/or lifetime of the device.

This data was taken using the JEDEC standard High-K test PCB.
Power rating is determined with a junction temperature of 125
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 and long term reliability.
