It features an advanced integrated feedback design and proprietary high- speed gate driver error correction (PurePath™ Ultra- HD). This technology allows ultra low distortion across the audio band and superior audio quality. The device can drive up to 2 x 100 W into 4- Ω load and 2 x 133 W into 3- Ω load and features a 2 VRMS analog input interface that works seamlessly with high performance DACs such as TI's PCM5242. In addition to excellent audio performance, TPA3245 achieves both high power efficiency and very low power stage idle losses below 0.8 W. This is achieved through the use of 60 m Ω MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
