These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The voltage slew rate of these pins must be restricted to no more than 10 V/ms. For higher slew rates, use a 100-k Ω resister in series with the pins. (3) The TPA3110D2 incorporates an exposed thermal pad on the underside of the chip. This acts as a heatsink, and it must be connected to a thermally dissipating plane for proper power dissipation. Failure to do so may result in the device going into thermal protection shutdown. See TI Technical Briefs SLMA002 for more information about using the TSSOP thermal pad. 4 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: TPA3110D2 |
