The TPA3126D2 is a 50-W, stereo, low-idle-current Class-D amplifier in a thermally enhanced package. The TPA3126D2 includes TI’s proprietary hybrid modulation scheme, which dynamically reduces idle current at low power levels to extend 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 prevent devices from being damaged during overload conditions.
