The TPA3137D2 device is an efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers at up to 6 W, 6 Ω, or 8 Ω (per channel).

Advanced EMI Suppression Technology with Spread Spectrum Control scheme enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction. The TPA3137D2 device is not only fully protected against shorts and overload, the SpeakerGuard™ speaker protection circuitry includes a power limiter and a DC detection circuit for protection of the connected speakers. The DC detect and Pin-to-Pin, Pin-to-Ground, and Pin-to-Power Short Circuit protection circuit protect the speakers from output DC and pin shorts caused in production. The outputs are also fully protected against shorts to GND, PVCC, and output-to-output. The short-circuit protection and thermal protection includes an auto recovery feature.

The TPA3137D2 device can drive stereo speakers with as low as 4-Ω impedance. The high efficiency of the TPA3137D2, 90% with an 8-Ω load, eliminates the need for an external heat sink, and TPA3137D2 will be able to output full power on a 2-layer PCB.
