NJW1112
8-IN 4-OUT STEREO AUDIO SELECTOR
„ GENERAL DESCRIPTION
The NJW1112 is an 8-input 4-output stereo audio selector.
It includes four independent 8-input-1output stereo audio selectors
and 0dB fixed gain buffers.
The NJW1112 performs superior audio characteristics such as low
distortion, low output noise and low crosstalk.
In addition, the NJW1112 is available to expand to 16-input
4-output stereo audio selector without sound quality deterioration,
because it is able to connect in parallel by Output switch function.
All of internal status and variables are controlled by three-wired
serial bus. Selectable two Chip address is available for using two
chips on same serial bus line. It is suitable for AV amplifiers, AV
receivers, Analog audio switchers, Video conferencing, Security
systems and others.
