The TDA1400 offers higher integration over previous Tripath amplifiers driver chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a given voltage rail. Additionally, the TDA1400 can be configured as a split supply, bridged amplifier, with the addition of some external components. The TDA1400 is capable of full range operation but the target application is subwoofers due to the high output power capability and single channel operation. Applications Home theater Subwoofers Car Audio Subwoofers Professional Active Speakers High Power consumer full-range amplifier Features Class-T architecture with proprietary DPP “Audiophile” Sound Quality Full Audio Bandwidth, 20Hz to 20kHz High Efficiency Supports wide range of output power levels and output loads by changing supply voltage and external Mosfets Compatible wi...
