Texas Instruments - Inductor-free stereo analog input class-D audio amplifier (TPA3138D2)

Texas Instruments TPA3138D2 is a 10W / ch, high efficiency, low idle current Class D stereo audio amplifier. It can drive stereo speakers with loads as low as 3.2 Ohm. In 1SPW mode, it consumes only 21mA (12V) of low idle current and can operate at 3.5V, enabling longer audio playback in battery-powered devices, Bluetooth speakers, and other power-sensitive applications And enhanced thermal performance. Advanced EMI suppression with spread spectrum control enables the use of economical ferrite bead filters while complying with EMC requirements to reduce system costs. To further simplify the design, the device incorporates basic protection features including overvoltage, undervoltage, power limit, short circuit, overheating, and DC speaker protection. All these protections come with automatic recovery.
