TPA3116D2DADR 50W Stereo Class D Audio Amplifier HTSSOP-32

The TPA3116D2DADR is a high-performance, filter-free Class D audio power amplifier designed for driving stereo speakers up to 50W per channel or a single mono speaker up to 100W. Part of Texas Instruments' TPA31xxD2 family, it features an advanced oscillator/PLL circuit with multiple switching frequency options to avoid AM interference and support master/slave synchronization. Its high efficiency (>90%) and low idle loss allow for a compact PCB design with minimal heat sinking requirements. Integrated SpeakerGuard™ protection circuits—including overtemperature, short-circuit, and DC-detect—ensure safe and reliable operation in demanding environments. Housed in a thermally enhanced 32-pin HTSSOP package, it is the premier choice for soundbars, home theater systems, and high-fidelity DIY audio projects.

Features:

• High Power Output: Delivers 2 x 50W into 4-Ohm loads or 100W in mono PBTL configuration.
• Efficient Class D Operation: Over 90% power efficiency reduces thermal management costs and extends battery life.
• AM Avoidance Technology: Multiple switching frequencies and synchronization prevent radio interference.
• Comprehensive Protection: Integrated thermal shutdown, short-circuit protection, and overvoltage lockout.
• Wide Supply Range: Operates reliably from a single 4.5V to 26V power source.
• Thermally Enhanced Package: HTSSOP-32 (DAD) with Pad-Up design for optimized cooling.
