The TPA3113D2 is a 6-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a virtual voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.

The TPA3113D2 can drive stereo speakers as low as 4 Ω. The high efficiency of the TPA3113D2, 87%, eliminates the need for an external heat sink when playing music.

The outputs are also fully protected against shorts to GND, VCC, and output-to-output. The short-circuit protection and thermal protection includes an auto-recovery feature.

TPA3113D2EVM — TPA3113D2 评估模块

TPA3113D2 是用于驱动立体声桥接式扬声器的 6W（每通道）高效 D 类音频功率放大器。高级 EMI 抑制技术使用户能够在输出端使用经济实惠的磁珠滤波器，同时又能满足 EMC 要求。SpeakerGuard™ 扬声器保护电路包含可调节功率限制器和 DC 检测电路。可调节功率限制器允许用户设置低于芯片电源电压的“虚拟”电压轨，以便限制通过扬声器的电量。DC 检测电路可以测量 PWM 信号的频率和振幅，如果输入电容器受损或者输入端出现短路，它就会关断输出级。

TPA3113D2 可以驱动低至 4Ω 的立体声扬声器。效率高达 87% 的 TPA3113D2 (...)
