TPA3250D2 High-Definition Class-D Amplifier

Texas Instruments TPA3250D2 High-Definition Class-D Amplifier enables true premium sound quality with class-D efficiency. This amplifier 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 32V power supply, the device can drive up to 2×130W peak into a 4Ω load and 2×70W continuous into an 8Ω load. The TPA3250D2 features a 2VRMS analogue input interface that works seamlessly with high-performance DACs such as TI's PCM5242. In addition to excellent audio performance, TPA3250D2 achieves both high power efficiency and very low power stage idle losses below 1W. This is achieved through the use of 60mΩ MOSFETs and an optimised gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
