Texas Instruments TPA3117D2 15W Power Amplifiers
Texas Instruments TPA3117D2 15W filter-free stereo Class-D audio power amplifiers with SpeakerGuard™ feature advanced EMI suppression technology that 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. TI TPA3117D2 audio power amplifiers can drive stereo speakers as low as 4Ω. The high efficiency of the TPA3117D2 eliminates the need for an external heat sink when playing music. These TI stereo Class-D audio power amplifiers are ideal for use in televisions, consumer audio equipment, and all-in-one computers.
