TPA2008D2

illustrate

The TPA2008D2 is a third-generation 5-V Class D amplifier with Texas Instruments. Improvements over the previous generation include: DC volume control, lower supply current, low noise layer, high efficiency, smaller package, fewer external components. Most notably, the new filterless Class-D modulation technique enables the TPA2008D2 to drive directly without the need for a low-pass filter output inductor and two capacitors to form three speakers per channel. Eliminating this output filter saves about 30% of the system cost and 75% of the PCB area.

Improvements and features make this LCD projector, LCD, powered speaker, and other applications ideal for devices that require more battery life, reduce board space, and perform better than existing Class D devices.
