The TPA3251D2 is a new product from Texas Instruments. It is a high-performance Class D power amplifier that achieves true high-quality sound quality with Class D efficiency.
The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra-HD). This technology achieves extremely low distortion across the entire audio frequency band and provides superior audio quality. The device can drive up to 2 x 175W under 4ohm load and 2 x 220W under 3ohm load. It has a 2 VRMS analog input interface and works seamlessly with high performance DACs such as TI PCM5242.
In addition to excellent audio performance, the TPA3251D2 also achieves high power efficiency and very low power stage idle losses below 1 W. This is achieved by using a 60mohm MOSFET and an optimized gate driver scheme, which has significantly reduced idle losses compared to a typical discrete implementation. , The company said.
