ADG465BRT屬于電路保護(hù)的TVS-混合技術(shù)。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADG465BRTTVS - 混合技術(shù)混合技術(shù) TVS（瞬態(tài)電壓抑制器）產(chǎn)品族中的產(chǎn)品屬于過(guò)壓保護(hù)產(chǎn)品，其中結(jié)合了基于多種技術(shù)的保護(hù)機(jī)制，例如串聯(lián)連接的 MOV（金屬氧化物壓敏電阻）和 GDT（氣體放電管），旨在同時(shí)獲得低漏電流和自恢復(fù)箝位工作特性。

GENERAL DESCRIPTION

The ADG465 is a single channel protector in an SOT-23 package. The channel protector is placed in series with the signal path, and will protect sensitive components from voltage transience in the signal path whether or not the power supplies are present. Because the channel protection works regardless of the presence of the supplies, the channel protectors are ideal for use in applications where correct power sequencing cannot always be guaranteed to protect analog inputs (e.g., hot-insertion rack systems). This is discussed further, and some example circuits are given, in the Applications section of this data sheet.
