NJM2174
AUDIO LINE AMPLIFIER with MUTE FUNCTION
s GENERAL DESCRIPTION
The NJM2174 is a low voltage audio line amplifier designed for
audio items.
Internal closed loop voltage gain is suitable for amplifier of small
line signal in digital audio items. It includes mute circuit
which realizes very low turn-noise at power on/off.
It is suitable for digital audio items with line out.
