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