Preliminary NJM2755 4-Input / 1-Output Stereo Audio Selector GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2755 is 4 Input / 1 Output Stereo Audio Selector. The NJM2755 consists of switches and buffer operational amplifiers. Based on the internal switch op-amp technology, the NJM2755 features lower output noise, lower distortion and NJM2755V higher channel separation than the general Multiplexers or Analogue Switches. The NJM2755 contains compatibility with NJM2752(2in-1out SW),NJM2753(3in-1out SW). APPLICATIONS LCD-TV/PDP-TV Car Stereo Any Audio System FEATURES Operating Voltage 4.7 to 10V 4 Input / 1 Output Stereo Audio Selectors Low Output Noise -114dBV typ. Low Distortion 0.0009% typ.
