2 INPUT/1 OUTPUT STEREO
AUDIO SELECTOR
DESCRIPTION
The UTC UM2752 is a Stereo Audio Selector with 2 Inputs and
1 Output. Based upon the inner OP-AMP Switch technology, the
UTC UM2752 features higher Channel Separation, lower Output
Noise and lower Distortion than the common Multiplexers or
Analogue Switches.
The UTC UM2752 can be applied to many kinds of audio
devices, such as Car Stereo, TV, Mini music center and so on.
FEATURES
* Dual Channel for Stereo Use
* 4.7~10V Operating Voltage
* 2 Input /1 Output Audio Selectors
* Bipolar Technology
* Low Output Noise: -114dBV typ.
* Low Distortion: 0.0009% typ.
