Hardware Overview
The TPA3244EVM PurePath™ Ultra-HD evaluation module demonstrates the TPA3244DDW integrated
circuit from Texas Instruments. The TPA3244DDW is a high-performance, high-power, class-D amplifier
that enables true premium sound quality with high-efficiency class-D technology. It features an advance
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 two BTL
(stereo 2.0) output channels, one PBTL (mono 0.1) output channel, one BTL plus two SE (2.1) output
channels, and four SE (4.0) output channel 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. The TPA3244EVM is a complete 2-V
RMS
analog
input 2 × 40-W continuous/2 × 100-W peak stereo high-power amplifier ready for evaluation and excellent
listening experience.
