TPA3244EVM

Оценочная плата, TPA3244 60Вт стерео/110Вт моно PurePath™ Ultra-HD усилитель звука класса D.

The TPA3244EVM from Texas Instruments is a 60W stereo / 110W peak PurePath ultra-HD analogue-in audio class-D pad-down module. The TPA3244EVM PurePath Ultra HD evaluation module demonstrates the TPA3244DDW IC. The TPA3244DDW 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 (PurePath 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 TPA3244DDW operation with differential or single ended input signals to the EVM with differential inputs yielding the optimal performance.
