The TPA3250 device is a high-performance class-D power amplifier. It operates with a 32 V power supply and delivers up to 2 x 130 W output power into a 4 Ohm load, or 2 x 70 W continuous output power into an 8 Ohm load. With a 2 VRMS analog input interface, it can be easily paired with high-performance DACs such as the TI PCM5242.In addition to excellent audio performance, the TPA3250 offers high power efficiency and a no-load power consumption of less than 1 W. This efficiency is achieved through the use of 60 mOhm MOSFETs and optimized gate driver solutions, which significantly reduce no-load losses compared to typical discrete devices.Basic parameters: 1.
