TPA3245 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. The device is operated in AD-mode, and
can drive up to 2 x 115 W into 4-Ω load and 2 x 145 W into 3-Ω load and features a 2 VRMS analog
input interface that works seamlessly with high performance DACs such as TIs PCM5242. In addition
to excellent audio performance, TPA3245 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.
