AD8112集成電路（IC）的模擬開關(guān)-特殊用途規(guī)格書PDF中文資料

AD8112屬于集成電路（IC）的模擬開關(guān)-特殊用途。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD8112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 AD8112 is a low cost, fully buffered crosspoint switch matrix that operates on ±12 V for audio applications and ±5 V for video applications. It offers a ?3 dB signal bandwidth greater than 60 MHz and channel switch times of less than 60 ns with 0.1 settling for use in both analog and digital audio. The AD8112 operated at 20 kHz has a crosstalk performance of ?83 dB and isolation of 90 dB. In addition, ground/power pins surround all inputs and outputs to provide extra shielding for operation in the most demanding audio routing applications. With a differential gain and differential phase better than 0.1 and 0.1°, respectively, and a 0.1 dB flatness output of up to 10 MHz, the AD8112 is suitable for many video applications.
