TPA3251D2DDV, Audio Amplifiers 175-W stereo, 350-W mono, 12- to 38-V supply, analog input Class-D Smart Audio Amplifier 44-HTSSOP 0 to 70
Semiconductors\Integrated Circuits - ICs\Audio ICs\Audio AmplifiersTPA3251D2 Ultra-HD Class-D Audio Amplifier
Texas Instruments TPA3251D2 Ultra-HD Class-D Audio Amplifier is a high-performance class-D power amplifier that enables true premium sound quality with class-D efficiency. 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 2x175W into 4Ω load and 2x220W into 3Ω load. It features a 2VRMS analog input interface that works seamlessly with high-performance DACs such as TI's PCM5242. In addition to excellent audio performance, the TPA3251D2 achieves both high power efficiency and very low power stage idle losses below 1W.
