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.

Application note:
Resistor(100k) and capacitor(1µF) connected to CNT1 are added to reduce pop-noise.
The value of input capacitor connected to IN1A and IN2A depends on cut-off frequency(calculated by fc=1/2πRC)
you need. R(input impedance)=100kΩ.
