■ 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.
