New Japan Wireless provides new solutions to improve the sound quality of audio equipment. It has launched three new audio ICs, electronic volume controller NJU72343, analog switches NJU72750A and NJU72751A, which can achieve high sound quality, low distortion and low noise.
ã€summary】
In order to achieve low distortion and low noise in audio equipment, audio selectors composed of electronic volume controllers and analog switches are now mainly used. The electronic volume controller NJU72343, analog switches NJU72750A and NJU72751A introduced this time are just to improve the performance of the audio selector and make the sound quality more beautiful and beautiful. These three products also use the new high-quality, low-distortion, low-noise circuit design technology and semiconductor manufacturing process technology of New Japan Wireless's original audio technology to develop a new solution to improve sound quality again.
In order to improve the sound quality of the sound, it is necessary to change the overall sound quality of the audio selector. The combination of these products can make the audio equipment achieve high sound quality, low distortion and low noise. Not only that, because they can be controlled by the same serial bus, according to the needs of different systems, you can flexibly call the required input and output signals and channels.
ã€main feature】
1. Realize high sound quality, low distortion and low noise
NJU72343 is an electronic volume controller that achieves low noise and improves the characteristics of total harmonic distortion to achieve high sound quality. NJU72750A and NJU72751A are analog switches that use low ON impedance switches. Low ON impedance switches can reduce the noise voltage and total harmonic distortion rate of audio equipment, thereby achieving high sound quality.
In the past, the analog switch used in the audio selector has a large ON impedance. In order to prevent the increase of the total harmonic distortion rate, the op amp is often connected to the rear of the analog switch. Both NJU72750A and NJU72751A have low ON impedance characteristics, which not only can omit the subsequent op amp and can achieve low distortion rate. No longer need to connect the op amp, there will be no interference of the op amp noise component, which is more conducive to achieving high sound quality and low noise.
2. Flexible system scalability
According to different system requirements, in order to be able to flexibly call the required input and output signals and channels, our product series have considered the expansibility that is convenient for multi-purpose use. With address selection terminals, you can use up to 2 NJU72343, 4 NJU72750A, 4 NJU72751A, and can use the same serial bus control.
