Class-D amplifier with low idle current offered in thermally enhanced package

The TPA3126D2, from Texas Instruments, is a 50W, stereo, low-idle-current Class-D amplifier in a thermally enhanced package. The device includes the company's proprietary hybrid modulation scheme, which dynamically reduces idle current at low power levels to increase the battery life of portable audio systems, like Bluetooth speakers. To further simply the design, the Class-D amplifier integrates full protection features including short circuit, thermal shutdown, overvoltage, undervoltage and DC speaker protection. Faults are reported back to the processor to stop devices from being damaged by overload conditions.
