NJU7391A
2-CHANNEL Audio Processor with eala surround
Q GENERAL DESCRIPTION
The NJU7391A is a 2-channel Audio Processor with 5-in 1-out
stereo audio selector, 2-band Tone Control and eala surround.
The NJU7391A performs low noise and low distortion
characteristics with resistance ladder circuit.
All of functions are controlled via three-wired serial bus.

(Note1) Pay attention to supply voltage not to exceed the absolute maximum power supply voltage by spike noise etc.
Because the difference between the absolute maximum power supply voltage and the operating voltage is small.
(Note2) EIA/JEDEC STANDARD Test board (76.2x114.3x1.6mm, 2layer, FR-4) mounting
(Note3) Don’t apply the input voltage that exceeds supply voltage.
