New Japan Radio releases the NJW1112, 8-input and 4-output stereo audio selector IC with output switch
October 1, 2009 - New Japan Radio Co., Ltd. has introduced to the market, the NJW1112,8-input and 4-output stereo audio selector IC with output switch, suitable for audio-video equipments such as AV/DVD receiver, audio router that have a lot of external input terminals.
[Background of development]
Recently, the increasing of multiple functionalities in AV/DVD receivers, demands for multi-input and multi-output audio selector.Usually, it is necessary to use serial connection of audio selectors on equipment with a dozen external input sources.But there is a loss of sound quality in this case. To solve problems, New Japan Radio has developed the NJW1112, the stereo audio selector providing high-quality sound by realizing parallel connection of multi-input audio selectors.
The NJW1112 is an audio selector, consists of 8-input and 4-output stereo switch, buffer amplifier, output switch. It is suitable for equipments with a lot of input terminals and a switching function of voice signals, such as AV receiver, DVD receiver, Audio router, Video Conferencing System, Security System. Moreover, it provides high-quality sound to the equipments by excellent audio characteristics.
- 1.Realizing parallel connection of multi-input audio selectors without sound quality loss
- The NJW1112 has built-in on/off switch at signal output part.It can realize parallel connection of the NJW1112s.It reduces deterioration of audio characteristics and provides high-quality sound to the equipments, as shown in fig1.
- 2.Providing high-quality sound to the equipments by excellent audio characteristics
- It realizes an excellent audio characteristics such as low distortion (THD=0.0007%) , low noise (VNO=-119dBV), low crosstalk (CT=120dB), and high channel separation (CS=116dB) ,based on our long term experience in analog circuit technology.
- 3.Providing high-quality sound by low ON resistance of 15-ohm
- It realizes low distortion of audio signal by low ON resistance of 15-ohm.
