NJW1111
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. ! FEATURES * Operating Voltage * 9-Input, 3-Output Stereo Audio Selector * Operating Current * Low Distortion * Low Output Noise * Low Crosstalk * Channel Separation * Variable Gain Buffer * 3-Wired Serial Control * Bi-CMOS Technology * Package Outline !
