The Texas Instruments TPA3250 device is a high-performance Class D power amplifier that delivers truly 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 superior audio quality in the audio band. Powered by a 32 V power supply, the device can provide up to 2 W x 130 W peak drive for 4 Ω loads or 2 W x 70 W continuous drive for 8 Ω loads with 2 VRMS analog input interface. It can be seamlessly connected with TI PCM5242 and other high-performance Dacs. In addition to excellent audio performance, the TPA3250 also achieves high power efficiency and no-load power consumption at a power level of less than 1 W. This is achieved through the use of a 60 mΩ MOSFET and an optimized gate driver scheme with much lower no-load losses than typical discrete devices.
