■ GENERAL DESCRIPTION
The NJM2776 is a low voltage headphone amplifier for portable audio applications.
The NJM2776 operates directly for one battery supply with independent power supply terminals (V+1 and V+2).
Also it provides shock-noise less standby mode.
The NJM2776 is suitable for portable MD, portable CD and others.
