60W stereo, 110W peak PurePath Ultra-HD down-class D amplifier 'TPA3244'
The TPA3244 is a high-performance power amplifier that achieves excellent sound quality with Class-D efficiency. It features an advanced integrated feedback design and a unique high-speed gate driver error correction function (PurePath Ultra-HD). This technology enables ultra-low distortion across the entire audio spectrum and outstanding audio quality. With a 30V power supply, it can drive 2 x 110W peak into a 4Ω load and 2 x 60W continuous output into an 8Ω load. Additionally, it includes a 2-VRMS analog input interface that operates seamlessly with high-performance DACs such as TI's Burr-Brown PCM52xx DAC family (PCM5242 / PCM5252). By using 65mΩ MOSFETs and an optimized gate driver method that significantly reduces idle losses compared to typical discrete implementations, it achieves excellent audio performance, high output efficiency, and low power stage idle losses of less than 0.45W. The package size is 6.1 x 14 mm HTSSOP. Evaluation modules and reference designs are also available. *For more details, please contact us.*
