| 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. s PACKAGE OUTLINE NJM2790V s FEARTURES q Operating Voltage q Operating Current q Maximum Output Voltage q Closed Loop Voltage Gain 4.5 to 5.5V 2.5mA typ. at V+=5V 4dBV typ. at THD=0.1% 3.5dB typ. at f=1kHz 2.5dB typ. at f=100kHz q Mute Function -85dB typ. q Supply Voltage Rejection Ratio 60dB typ. q Bipolar Technology q Package Outline SSOP14 s PIN CONFIGURATION 1 2 3 4 5 6 7 14 13 12 11 10 9 8 PIN FUNCTION 1.
