Description

fenlan The TPA3250 device is a high-performance -D power amplifier delivers true high- sound with -D efficiency. The device features an advanced integrated feedback design and proprietary high-speed gate driver correction (Purepath Ultra-HD). This technology enables ultra-low distortion and superior audio in the audio frequency band. The device operates from a 32V supply Power supply, can up to 2W*130W drive to 4ohm load, or 2W*70W continuous drive to 8ohm load, and has 2 VRMS analog input interface, which can be seamlessly matched with high-performance DACs such as TI PCM5242. Audio performance, the TPA3250 also achieves efficiency and power no-load power dissipation 1 W. This is achieved by using 60 mohm MOSFETs and an optimized gate driver scheme with much lower no-load losses than typical discrete devices.
