Texas Instruments TPA3250 | Demoboard TPA3250D2EVM

Description

The TPA3250D2EVM Ultra-HD evaluation module demonstrates the TPA3250D2DDW integrated circuit from Texas Instruments. The TPA3250D2DDW 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 (Ultra-HD), 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 TPA3250D2DDW operation with differential or single ended input signals to the EVM with differential inputs yielding the optimal performance. TPA3250D2EVM is a complete 2Vrms analog input 70 W stereo continuous/130W peak power amplifier ready for evaluation and excellent listening experience.
