Product introduction:
The TPA3250 device is a high-performance Class D power amplifier, which can achieve high-quality sound effects with Class D efficiency. The device is equipped with advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra-HD) This technology enables ultra-low distortion and superior audio quality in the audio frequency band. The device is powered by 32 V power supply, and can provide up to 2 W x 130 W peak drive for 4 loads, or 2 W x 70 W continuous drive for 8 loads. It also has 2 VRMS analog input interfaces, which can be seamlessly connected with high-performance DACs such as TI PCM5242. In addition to excellent audio performance, the TPA3250 also achieves high power efficiency and power level no-load power consumption of less than 1 W. This is achieved by using 60 m MOSFET and optimized gate driver, which has much lower no-load loss than typical discrete devices
