The TPA3244 device is a high performance Class-D power amplifier that enables true
premium sound quality with Class-D efficiency. It features an advanced integrated feedback design
and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology allows ultra low
distortion across the audio band and superior audio quality. With a 30-V power supply the device
can drive up to 2 x 110 W peak into 4-Ω load and 2 x 60 W continuous into 8-Ω load and features a
2-VRMS analog input interface that works seamlessly with high performance DACs such as Burr-Brown
PCM52xx DAC Family from TI (that is, PCM5242 / PCM5252). In addition to excellent audio
performance, TPA3244 achieves both high power efficiency and very low power stage idle losses below
0.45 W. This is achieved through the use of 65 mΩ MOSFETs and an optimized gate driver scheme that
achieves significantly lower idle losses than typical discrete implementations.
