描述 Description

The NS5S1153 is a DPDT switch for combined true-ground audio and USB 2.0 high speed data applications. It allows portable systems to use a single port to pass either USB data or audio signals from an external headset; headset; the 2 channels being compliant to USB 2.0, USB 1.1 and USB 1.0. The switch is capable of passing signals with negative voltages as low as 2 V below ground. The device features shunt resistors on the audio ports. These resistors are switched in when the audio channel is off and provide a safe path to ground for any charge that may build up on the audio lines. This reduces Pop and Click noise in the audio system. The NS5S1153 is also equipped with VBUS detection circuitry to immediately switch to USB mode in the event that a voltage is detected on VBUS. The NS5S1153 is housed in a space saving, ultra low profile 1.4 x 1.8 x 0.5 mm 10 pin UQFN package.

簡介

NS5S1153屬于集成電路（IC）的模擬開關(guān)-特殊用途。由制造生產(chǎn)的NS5S1153模擬開關(guān) - 特殊用途特殊用途模擬開關(guān)通過固態(tài)設(shè)備路由模擬信號。該系列產(chǎn)品的與眾不同之處在于，這些模擬開關(guān)針對特定的應(yīng)用，因此具有通用模擬開關(guān)通常所沒有的獨特功能。
