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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(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) 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.
(3) The absolute maximum temperature under any condition is limited by the constraints of the silicon process.
(4) 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.

(1) This data was taken using the JEDEC standard High-K test PCB.
(2) 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.
