2Vrms Ground Referenced Stereo Line Amplifier with LPF
Q GENERAL DESCRIPTION
The NJU72013 is an audio line Amplifier . It can swing 2Vrms
(5.6V peak-to-peak) signal at 3.3V operating voltage.
Ground-referenced outputs eliminate output coupling capacitor.
The pop noise suppression circuit removes a pop noise at the
power-on and power-off.
It is suitable for audio line interface of audio equipment which
does not have over 9V regulator.

1.1.2 Flying capacitor (C4)
Use capacitors with a low-ESR (ex. ceramic capacitors) for optimum performance. Design to provide
low impedance for the wiring between CP terminal (4pin), CN terminal (5pin), and the flying capacitor
(C4).
C4=1uF
CP(4pin)
CN(5pin)

1.1.3 Hold capacitor (C6)
Use capacitors with a low-ESR (ex. ceramic capacitors) for optimum performance. Design to provide
low impedance for the wiring between the hold capacitor (C6), V- terminal (6pin) and the GND on the
PCB.
Separate the GND pattern connecting to the hold capacitor (C6) from that connecting to the GND
terminal (8pin), thus suppressing the influence of switching noise by removing the common impedance
of the GND wiring.
Design no short-circuits of V- terminal (6pin) and V+ terminal (3pin) on the PCB pattern.

GND(8pin)
