Product Summary
The TPA2000D2PWR is a monolithic class-D power IC stereo audio amplifier, using the high switching speed of power MOSFET transistors. The TPA2000D2PWR is the third generation 5-V class-D amplifier from Texas Instruments. Improvements to previous generation devices include: lower supply current, lower noise floor, better efficiency, four different gain settings, smaller packaging, and fewer external components. The most significant advancement with this device is its modulation scheme that allows the amplifier to operate without the output filter. Eliminating the output filter saves the user approximately 30% in system cost and 75% in PCB area.
