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