    1. ADUM1400 Inputs enable behaviour

      Forum Thread
      Answered
      Interface and Isolation
      14 November, 2011
      Hi, I have found a strange behaviour in the ADUM1400BRWZ: the datasheet says the pin 7 shouldn't be connected but if I don't connect it the inputs are disabled. Then I tried to connect pin 7 first to GND1 and then change it to VDD1 to see the …

      29 May, 2014
      Hi, We are using ADuM1401BRWZ in our design on a SPI bus. Currently we are able to read and write data at 4MHz clock. When we increase the clock speed to 8MHz we are unable to get the proper data. As per the part no ADuM1401BRWZ is supposed to operate …

    4. Do ADUM1402BRWZ and ADUM3400CRWZ have logic low or logic high fail-safe output ?

      Docs & FAQs
      Interface and Isolation
      There is no fail safe on these parts. Output will reflect the voltage on the input side given both sides are powered. On ADUM340x, if VIx > 2.0 V , output will be high. If VIx 1.6 V, output will be high. If VIx < 0.4V, output will be low …

      Hello Chiranjeevi M, I wanted to update you on a new family of digital isolators optimized specifically for SPI communications. The ADuM315x and ADuM415x SPIsolatorTM family was released to the market recently. You can find more information on the different features and performance at this web page: analog.com/spisolator …

      Hello Chiranjeevi M, The maximum throughput in an isolated SPI interface is determined by the round-trip delay through the isolator rather than the maximum throughput. This is because the clock must be received by the slave and transmitted back to the master in less than one half of the …

      Hello I have been using ADUM1400CRWZ for several years in my product but it is unavailable now. The ADUM140E0BRWZ seems to be a perfect replacement but I am just worrying about the CE certificate. The rise and fall times are 2.5ns for both circuits and therefore I assume it …
