Hello ,

Our customer found the ADG1607 symbol data is not correct.

 http://www.analog.com/media/en/symbols-footprints/symbols/ADG1607BCPZ-REEL7.bxl 

The pin assingment of the symbol is for ADG1606.

Our customer wants to get correct symbol data.

Could…

Hi,

I am asking advice on the following issue:

In order to build a multiplexed 4-wire resistance measurement I connected two ADG1607 as seen in the attached figure. A constant current AC signal ( 16 kHz ) is connected to the EXCITE_A and EXCITE_B terminals…

Hello.

It is connected to Aducm363 I/O port for 16:1 Mux Selection.

There are 16 temperature sensors connected to the MUX.

Note. ADG1607 16:1 Mux product was used.

I want to obtain data from the first temperature sensor connected to the MUX through…

      最近我在项目上采用了AD7124-4芯片进行PT100温度传感器采集温度，采集效果还不错，采用比例测量法。外部用ADG1607模拟开关来进行通道切换。

      但是我看ADI给的参考设计都是AD7124的PIN管教直接连接PT100传感器，我的设备传感器连接线缆超过1米，因此我担心ESD干扰或者其他的信号对AD7124

造成损坏，我看一般的建议是加限流电阻、TVS和ADG5243F进行保护，但是ADG5243F成本太高了，不知道还有没有其他的方法对AD7124进行保护呢？
