The TPA3250 device is a high-performance class-D amplifier. The device uses a 32 V supply and can provide up to 2 W x 130 W drive to a 4 Ohm load, or 2 W x 70 W continuous drive to an 8 Ohm 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 efficiency and no-load consumption of less than 1 W level.This is achieved through the use of 60 mOhm MOSFETs and optimized gate driver solutions, which have much lower no-load losses than typical discrete devices.Basic parameters:1.
