... Stereo Audio Selector 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 ...
