TPA3156D2 Analog Input Class-D Amplifier

Texas Instruments TPA3156D2 Analog Input Class-D Amplifier has low idle power loss and helps to extend the battery life of BLUETOOTH®/Wireless speakers and other battery-powered audio systems. The high efficiency of the TPA3156D2 device allows it to do 2x70W with an external heat sink on a dual-layer PCB. This device integrates 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 multiple switching frequency options to avoid AM interferences. This feature is achieved with the master or slave option, making it possible to synchronize multiple devices. The Texas Instruments TPA3156D2 is fully protected against faults with short-circuit protection and thermal protection as well as over voltage, under voltage, and DC protection. Faults are reported to the processor to prevent devices from being damaged during overload conditions.
