8.3.1.3 Optimizing Thermal Performance

Follow the Layout Example section to achieve the best balance of design size, thermal, audio, and electromagnetic performance. In some cases, deviation from this guidance can be required due to design constraints which cannot be avoided. The system designer maintains that the heat can get out of the device and into the ambient air surrounding the device. The TAS5830 device utilizes a TSSOP-DAD, pad up, package to maximize the thermal dissipation away from the device. Heat is transferred from the device to the ambient air through a low impedance heat sink path. The use of a heat sink is required. TI recommends using ATS-TI10P-519-C1-R3 from www.qats.com, shown in Figure 8-4. The size of the heat sink can deviate from the suggested heat sink in space constrained environments, but thermal performance can degrade.
