• ADuM4190 specification


    I have some questions about ADuM4190 from the customer.

    He is in trouble because he cannot choose what parts are suitable for his design.
    Datasheet specifies Noise,EAout and Noise,EAout2 under the condition of Figure 29. Test Circuit 3.

    1. Do you…

  • ADUM4190 design question

    Hi Sir,

    I have question regarding to ADUM4190.

    There is two schematic by ADUM4190 and use 5V with VCC_P and P+5V.

    Up one of schematic use OPA in ADUM4190 as voltage follower, Can I supply 3.3V to Gen_V for +IN than get output 3.3V from EAout?

    Below one…

  • ADuM4190 input impedance


    I have a question on ADuM4190.

    What is the input impedance of the ADuM4190?

    I want input impedance to be 22kΩ or more.

  • ADUM4190 applicaion issue

    Hi ADIexpert

    I would like to use the refout1 of ADUM4190 as a voltage reference to my other circuits in the schematic

    I connected the REfout1 to the non invert pin of a TL074 to build a voltage follower without attaching any loading on the output of TL074…

  • ADuM4190 isolation amplifier

    I am interested in using the ADuM4190 isolation amplifier but I am not sure what voltage difference I can put across the device. In my measurement system I need to measure input signals that are at -4kV dc with respect to the output. Please can you tell…

  • About ADUM4190 spec

    Hi there,

    I have a question about ADUM4190.

    According to the datasheet, output gain(COMP to EAout) is :0.83(min) -1(typ)- 1.17(Max).

    Does this spec include the temperature variation?

    I also want to make sure the same things on offset voltage spec…

  • ADUM4190 Input voltage range


    Could you teach me about the input voltage range of ADUM4190 ?

    I can not find the description of input voltage range in the datasheet. 

    I thought that input voltage range of ADUM4190 means input common mode  range (0.35V~1.5V)  desiceibed in the datasheet…

  • Instead of using voltage transformer to monitor three phase voltage i am planning to use ADuM4190 isolation amplifier. I am not able to find application not for ADuM4190. please suggest

    I want to eliminate one voltage transformer in my design. which measures phase voltage. I saw datasheet of ADuM4190, which clearly tells application as voltage monitoring & also it provides complete isolation between input side & output side. I am looking…

  • Use ADuM4190 for isolate voltage measuring.

    Hello, is it possible to use the ADuM4190 for the purpose of AC and DC voltage measurement?

    The intention is to use a circuit similar to "Figure 29. Test Circuit 3: Isolated Amplifier Circuit" to get the values of a voltage divider, the values results…

  • Non linearity issue wrt temperature in ADuM4190?

    How to get the temperature compensation output in the ADUM4190? and is it non linear?
