Class-D audio amplifier for driving bridged-tied stereo speakers

Available from Mouser, Texas Instruments TPA3136D2 Class-D audio amplifier is for driving bridged-tied stereo speakers at up to 10W, 6ohm, or 8ohm (per channel). The 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 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. Typical applications include televisions, Bluetooth/wireless speakers, mini speakers, USB speakers and consumer audio equipment.
