The TPA3251EVM Ultra-HD evaluation module demonstrates the TPA3251 integrated circuit from Texas Instruments. The TPA3251 is a high-performance Class-D amplifier that enables true premium sound quality with high efficiency Class-D technology. It features an advanced integrated feedback design and high-speed gate driver error correction, which enables ultra-low distortion across the audio band and superior audio quality.
This EVM supports 2 BTL (stereo 2.0) output channels, 1 PBTL (mono 0.1) output channel, 1 BTL plus 2 SE (2.1) output channels, and 4 SE (4.0) output channels configurations. The NE5532 is a High Performance Audio Op Amp designed to allow TPA3251 operation with differential or single ended input signals to the EVM with differential inputs yielding the optimal performance. TPA3251EVM is a complete 2Vrms analog input 2 × 175 W stereo/1 x 350 W mono power amplifier ready for evaluation and excellent listening experience.
