TPA3140D2PWPR

TPA3140D2 Class-D Audio AmplifierTexas Instruments TPA3140D2 Class-D Audio Amplifier is an efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers at up to 10W/6Ω or 8Ω (per channel). This device from Texas Instruments comes with Advanced EMI Suppression Technology with Spread Spectrum Control and 1SPW modulation scheme. This enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction. This device is protected against shorts and overload. The SpeakerGuard™ speaker protection circuitry includes an adjustable Automatic Gain Limit (AGL), an adjustable power limiter and a DC detection circuit for protection of the connected speakers. The AGL allows adjustment of the maximum output voltage without signal clipping. This provides for enhanced speaker protection and audio quality. 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.
