NJU26904
Digital Audio Delay
■ General Description
The NJU26904 offers digital audio delay.
The NJU26904 has internal delay memory. Delay function can adjust output
time of a six-channel signal.
This delay functions are suitable for delay time adjustment such as Audio
products and time alignment such as Car Audio.
