Product Introduction

This power amplifier module samples two original imported TPA3116D2 digital power amplifier chips, one of which is used as a left and right channel power amplifier, and the other is connected to the NE5532 front bridge to drive heavy bass. It has the characteristics of small size, high efficiency, high power, and low heat generation.

NE5532 is a high-performance low-noise dual operational amplifier (dual op amp) integrated circuit. Similar to many standard operational amplifiers, it has better noise performance, excellent output driving capability, relatively high small signal bandwidth, and a wide power supply voltage range. Therefore, it is very suitable for application in high-quality and professional audio equipment, instruments, control circuits, and telephone channel amplifiers. When used as an audio amplifier, it has a warm tone and high fidelity. In the early 1990s, it was praised by audiophiles as the "king of operational amplifiers" and is still one of the essential operational amplifiers in the hands of many audiophiles today.
