9-Input 3-Output Stereo Audio Selector
! GENERAL DESCRIPTION
The NJW1111 is a 9-input 3-output stereo audio selector.
It includes three independent 9input-1output stereo audio selectors
and adjustable gain buffers.
The NJW1111 performs superior audio characteristics such as low
distortion, low output noise and low crosstalk.
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 amplifier and
receiver system and others.
