NJM2790
AUDIO LINE AMPLIFIER with MUTE FUNCTION
s GENERAL DESCRIPTION
The NJM2790 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.
The NJM2790 is 6.5dB closed loop voltage gain, another
version of 3.5dB is the NJM2174.
It is suitable for digital audio items with line out.
