NJM2752
2-Input / 1-Output Stereo Audio Selector
s GENERAL DESCRIPTION The NJM2752 is 2-Input / 1-Output Stereo Audio Selector. The NJM2752 consists of switches and buffer operational amplifiers. Based on the internal switch op-amp technology, the NJM2752 features lower output noise, lower distortion and higher channel separation than the general Multiplexers or Analogue Switches. The NJM2752 contains compatibility with NJM2753 (3in-1out SW), NJM2755 (4in-1out SW). It is suitable for LCD-TV / PDP-TV, Car Stereo, and Any Audio System. s PACKAGE OUTLINE
