Ver.2.1
2-Input / 1-Output Stereo Audio Selector
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
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 the NJM2753 (3in-1out
SW), NJM2755 (4in-1out SW). It is suitable for LCD-TV/PDP-TV, Car
Stereo, and Any Audio System.
■ FEATURES
● Operating Voltage 4.7 to 10V
● 2-Input / 1-Output Stereo Audio Selectors
● Low Output Noise -114dBV typ.
● Low Distortion 0.0009% typ.
● Bipolar Technology
● Package Outline MSOP10 (TVSP10)*
