This amplifier module samples two TPA3116D2 digital amplifier chips, one of which serves as a left and right channel power amplifier, and the other is pre bridged with NE5532 to drive subwoofers. Featuring small size, high efficiency, high power, and low heat generation
NE5532 is a high-performance low noise dual operational amplifier (dual operational amplifier) 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 range of power supply voltages. Therefore, it is very suitable for application in professional audio equipment, instruments, control circuits, and telephone channel amplifiers. When used as an audio amplifier, the sound quality is warm and the fidelity is high. In the early 1990s, it was praised by audiophiles as the “”king of amplifiers”” and is still one of the essential amplifiers in the hands of many audiophiles.
