Product Description：

The Texas Instruments TPA3250 device is a high-performance Class D power amplifier that delivers true high-quality sound with Class D efficiency. The device features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath™ Ultra-HD). This technology enables ultra-low distortion and outstanding audio quality in the audio band. Powered by a 32 V supply, the device delivers up to 2 W x 130 W peak drive to a 4 Ω load or 2 W x 70 W continuous drive to an 8 Ω load, and features a 2 VRMS analog input interface for seamless mating with high-performance DACs such as the TI PCM5242. In addition to excellent audio performance, the TPA3250 also achieves high power efficiency and no-load power consumption of less than 1 W at the power stage. This is achieved by using a 60 mΩ MOSFET and optimized gate driver scheme, with much lower no-load losses than typical discrete devices.
