ABSOLUTE MAXIMUM RATINGS
TPA721
SLOS231E – NOVEMBER 1998 – REVISED JUNE 2004
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

In the D package, the maximum output power is thermally limited to 350 mW; 700 mW peaks can be
driven, as long as the RMS value is less than 350 mW.

The D and DGN packages are available taped and reeled. To order a taped and reeled part, add the
suffix R to the part number (e.g., TPA301DR).

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.
