NS5S1153 Double Pole Double Throw Switch

The NS5S1153 integrated circuit is a DPDT (Double Pole Double Throw ) switch for combined true−ground audio and USB 2.0 high speed data applications. NS5S1153 allows portable systems to use a single port to pass either USB data or audio signals from an external headset. The switch is capable of passing signals with negative voltages as low as 2 V below ground.

The NS5S1153 is equipped with many features like  : low RON audio /data DPDT switch , capable of passing negative swing signals down to −2 V , 1.8 V compatible control pin for 2.7 V ≤ VCC ≤ 4.2 V , high USB path bandwidth (>900 MHz) , VBUS detection circuitry for automatic switching between audio and USB modes , audio channel shunt resistors for pop & click noise reduction , ultra−low THD in audio mode: 0.01% into 16 ohms load .
