NJM2179
SRS 3D SURROUND AUDIO PROCESSOR
GENERAL DESCRIPTION The NJM2179 is a SRS 3D surround audio processor regenerating the 3D surround sound by two speakers. It regenerates 3D surround sound from only stereo input. The features of wide operating voltage range, wide dynamic range, low output noise are suitable for any audio applications. PACKGE OUTLINE
NJM2179D FEATURES Operating Voltage (4.7 to 13V) Low Supply Current (7mA typ. at 3D-STEREO mode) Wide Dynamic Range (>110dB) Low Output Noise (22µVrms typ. at 3D-STEREO mode) BYPASS Gain (-3dB typ.) BYPASS FUNCTION(Through) SPACE and CENTER control Internal Mode Control Switch Bipolar Technology Package Outline DIP16,DMP16
