• RE: SPDT

    Hi,

    Thanks for getting in touch.

    The ADG5243F is an triple SPDT switch. however the maximum operating voltage is 44 V.

    Can you share more details about your application and why you require up to 46 V?

    Regards,

    David

  • 关于ADC芯片 AD7124-4的前端电路保护问题！！

          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？

  • RE: ADG1234 analog inputs clamping diodes

    Hi David,

    At first flance, the ADG5243F looked good for our application.

    Unfortunately, we needed to use the switch in a SPDT configuration (with

    the high voltage on the SP side), so this IC does not fit.

    In the end we have completely changed the…

  • What happens to the output during an over-voltage event?

    Q 

    What happens to the output during an over-voltage event?

     

    A 

    The drain output will be clamped during an overvoltage fault condition. The
    ADG5248F, ADG5249F, and ADG5243F have secondary supplies (POSFV, NEGFV) which
    will be the clamp voltages…

    Q 

    Are these parts pin-pin compatible with existing parts?

     

    A 

    Yes, the ADG5208F/ADG5209F are pin-for-pin compatible with the ADG5208/ADG5209
    and ADG1208/ADG1209. They are drop in replacements if overvoltage protection is
    required. However…

    Apologies for the delay, See below for the ADG5243F

               

    Θjb = 16.67°C/W

    Rjc for exposed paddle packages is normally measured to the exposed paddle.
