TPA3117D2中文资料带 SpeakerGuard™、支持无滤波器操作的 15W 立体声、8V 至 26V 电源电压、模拟输入 D 类音频放大器数据手册TI规格书

描述 Description

The TPA3117D2 is a 15W (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. 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 TPA3117D2 can drive stereo speakers as low as 4. The high efficiency of the TPA3117D2, 90%, 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.
