Class-D amplifiers are more efficient than traditional class-AB<br />
amplifiers since they waste less power as heat. Class-D amplifiers<br />
have experienced huge growth in recent years since they provide<br />
portable audio applications with longer battery life and enable higherpower<br />
audio applications to reduce if not eliminate heat-sinking<br />
requirements.<br />
TI continues to build on its industry-leading class-D portfolio designed<br />
for both the lower-power portable market and the higher-power<br />
segment.<br />
The newest addition to TI’s class-D higher-power portfolio is the<br />
TPA3120D2.<br />
Class-D <strong>Audio</strong> Power Amplifiers<br />
Key Features<br />
• 25 W of output power per channel into 4 Ω<br />
• 90% efficient class-D operation eliminates the need for external<br />
heat sink.<br />
• Operation from a wide supply voltage (10-30 V) reduces the need for<br />
additional power supply.<br />
• Four gain settings (20, 26, 32 and 36 dB) for flexible system<br />
operation<br />
• Single-ended outputs reduce the size of the output filter.<br />
• Packaging: 24-pin HTSSOP (PowerPAD)<br />
Applications<br />
• Flat-panel TVs (see System Block Diagram on page 21)<br />
• Home theaters<br />
