3-Input 1-Output Stereo Audio Selector
GENERAL DESCRIPTION NJM2753 3-Input 1-Output Stereo Audio Selector. NJM2753 consists switches buffer operational amplifiers. Based internal switch op-amp technology, NJM2753 features lower output noise, lower distortion higher channel separation than general Multiplexers Analogue Switches. NJM2753 contains compatibility with NJM2752(2in-1out SW),NJM2755(4in-1out SW). sAPPLICATIONS qLCD-TV/PDP-TV qCar Stereo qAny Audio System FEATURES Operating Voltage 3-Input 1-Output Stereo Audio Selector Output Noise Distortion Bipolar Technology Package Outline PACKAGE OUTLINE
