AD8108AST集成電路（IC）的模擬開關(guān)-特殊用途規(guī)格書PDF中文資料

AD8108AST屬于集成電路（IC）的模擬開關(guān)-特殊用途。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD8108AST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。

GENERAL DESCRIPTION

The AD8108/AD8109 are high speed 8 × 8 video crosspoint switch matrices. They offer a ?3 dB signal bandwidth greater than 250 MHz and channel switch times of less than 25 ns with 1 settling. With ?83 dB of crosstalk and ?98 dB isolation (@5 MHz), the AD8108/AD8109 are useful in many high speed applications.

FEATURES

8 × 8 high speed nonblocking switch arrays

AD8108: G = 1

AD8109: G = 2

Serial or parallel programming of switch array

Serial data out allows daisy-chaining of multiple 8 × 8 arrays

to create larger switch arrays

Output disable allows connection of multiple devices

Pin-compatible with AD8110/AD8111 16 × 8 switch arrays

For 16 × 16 arrays see AD8116
