AD8108集成电路（IC）的模拟开关-特殊用途规格书PDF中文资料

AD8108属于集成电路（IC）的模拟开关-特殊用途。由亚德诺半导体技术有限公司制造生产的AD8108模拟开关 - 特殊用途特殊用途模拟开关通过固态设备路由模拟信号。该系列产品的与众不同之处在于，这些模拟开关针对特定的应用，因此具有通用模拟开关通常所没有的独特功能。

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
