Features: The TPA3250 device is a high-performance class-D power amplifier. The device uses a 32 V power supply and can provide up to 2 for W x 130 for W for peak drive to a 4 Ω load, or 2 for W x 70 for W continuous drive to an 8 Ω load, and With 2 VRMS analog input interface, it can be seamlessly matched with TI PCM5242 and other high-performance DACs. In addition to excellent audio performance, TPA3250 also achieves high power efficiency and no-load power consumption of less than 1 for W power level. This is achieved through the use of 60 mΩ MOSFETs and optimized gate driver solutions, which have much lower no-load losses than typical discrete devices. The electrolytic capacitor signal main circuit adopts a patch electrolytic capacitor with a capacity of 4×220UF, which ensures strong and continuous power support.
