Image of Texas Instruments' TPA3156D2 Analog Input, Class-D Amplifiers Texas Instruments' TPA3156D2 have low idle power loss and help to extend the battery life of Bluetooth^®/wireless speakers and other battery-powered audio systems. The TPA3156D2's high efficiency allows it to do 2 x 70 W with an external heat sink on a dual layer PCB. These devices integrate an efficiency boost mode, which dynamically reduces the current ripple of the external LC filter and the idle current.

The TPA3156D2 advanced oscillator/PLL circuit employs a multiple switching frequency option to avoid AM interferences, which is achieved together with an option of either master or slave, making it possible to synchronize multiple devices.

The TPA3156D2 devices are fully protected against faults with short-circuit and thermal protection as well as overvoltage, undervoltage, and DC protection. Faults are reported back to the processor to prevent devices from being damaged during overload conditions.

Features
2 x 70 W into a 4 Ω BTL load at 24 V Wide voltage range: 4.5 V to 26 V Efficient Class-D operation Very low idle current: <23 mA for recommended LC filter configurations Greater than 90% power efficiency Adaptive modulation schemes based on output power Multiple switching frequencies AM avoidance Master and slave synchronization 300 KHz to 1.2 MHz switching frequency		Feedback power-stage architecture with high PSRR reduces PSU requirements Programmable power limit Parallel BTL mode and mono-channel mode support Supports both single and dual power supply modes Integrated self-protection circuits including overvoltage, undervoltage, overtemperature, DC-detect, and short circuit with error reporting Thermally enhanced packages DAD (32-pin HTSSOP pad up) Pin-to-pin compatible with TPA3116D2 and TPA3126D2
Applications
Bluetooth/wireless speakers Soundbars		Mini-micro component, docks Home theaters
