NJW1110
9-Input 3-Output Stereo Audio Selector
! GENERAL DESCRIPTION
NJW1110 is a 9-input 3-output stereo audio selector.
It includes three independent 9input-1output stereo
audio selectors and adjustable gain buffers.
NJW1110 performs superior audio characteristics
such as low distortion, low output noise and low
crosstalk. All of internal status and variables are
controlled by I²C BUS interface. And the slave
address selector is available for using two chips on
same serial Bus line. It is suitable for latest TV system
and others.
