AD8115AST集成電路（IC）的模擬開關(guān)-特殊用途規(guī)格書PDF中文資料

AD8115AST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AD8115AST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(hào)。該系列產(chǎn)品的與眾不同之處在于，這些模擬開關(guān)針對(duì)特定的應(yīng)用，因此具有通用模擬開關(guān)通常所沒有的獨(dú)特功能。

GENERAL DESCRIPTION

The AD8114/AD81151 are high speed 16 × 16 video crosspoint switch matrices. They offer a ?3 dB signal bandwidth greater than 200 MHz and channel switch times of less than 50 ns with 1 settling. With ?70 dB of crosstalk and ?90 dB isolation (@ 5 MHz), the AD8114/AD8115 are useful in many high speed applications. The differential gain and differential phase of better than 0.05 and 0.05°, respectively, along with 0.1 dB flatness out to 25 MHz while driving a 75 ? back-terminated load, make the AD8114/AD8115 ideal for all types of signal switching.

FEATURES

16 × 16 high speed nonblocking switch arrays

AD8114; G = 1

AD8115; G = 2

Serial or parallel programming of switch array

Serial data out allows daisy-chaining of multiple

16 × 16 arrays to create larger switch arrays

High impedance output disable allows connection of

multiple devices without loading the output bus

For smaller arrays see the AD8108/AD8109 (8 × 8) or

AD8110/AD8111 (16× 8) switch arrays
