Texas Instruments  TPA3245DDV

TPA3245 is a high performance class-D power amplifier that enables true premium soundquality with class-D efficiency. It features an advanced integrated feedback design and proprietaryhigh-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra lowdistortion across the audio band and superior audio quality. The device is operated in AD-mode, andcan drive up to 2 x 115 W into 4-Ω load and 2 x 145 W into 3-Ω load and features a 2 VRMS analoginput interface that works seamlessly with high performance DACs such as TI’s PCM5242. In additionto excellent audio performance, TPA3245 achieves both high power efficiency and very low powerstage idle losses below 0.45 W. This is achieved through the use of 65 mΩ MOSFETs and an optimizedgate driver scheme that achieves significantly lower idle losses than typical discreteimplementations.
