NJM2753

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 q LCD-TV/PDP-TV q Car Stereo q Any 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 NJM2753V 4.7 to 10V -114dBV typ. 0.0009% typ.
