TPA3137D2 Class-D Audio Amplifier

Texas Instruments TPA3137D2 Class-D Audio Amplifier is an efficient, Class-D audio power amplifier. This amplifier is for driving bridged-tied stereo speakers at up to 6W, 6Ω, or 8Ω (per channel). Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction. The TPA3137D2 device is fully protected against shorts and overload. Also, 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.
