• ADG442: low logic level clamped to about -1V.

    Q 

    In my prototype, ADG442 is not  The problem seems to be that the digital inputs
    are driven with +15V and -15V logic levels, but the ADG442s are clamping the
    low logic level to about -1V. The data sheet (rev. A, 2005) gives the maximum

  • ADG5404, ADG1406, ADG442: case temperature:

    Q 

    Pls advise the case temperature of below ADI devices:

    For the switch/multiplexer parts the max case temperature can be calculated as
    follows:
    Tc = Tj - Pd x Thetajc

  • ADG442 case size

    Hi, since this is my first post on analog devices forum, I would like to introduce myself.

    My name is Robert and i work at Michigan state university.

    I am designing integrating type of light detector so i decided to use bilateral switch to reset integrating…

  • RE: The misbehavior of the spice model of ADG721.cir

    Hi Jo,

    I'm glad that you have found the ADG442 to better cater your quad input aplication.

    To verify your observations, I did try to check the model and had a quick simulation. I can confirm you are correct and thank you for bringing this to our attention…

  • RE: CN0209 Accuracy error

    Thanks Derrick this error is similar to what I am measuring both in the evaluation board and in our board.

    Still I would like to know the configurations and formulas for the rest of interfaces if possible.

    I have another question. Is it possible to…

    Hi Divya,

    For quick reference, here is a link to the circuit note: http://www.analog.com/cn0209

    In CN0209, the purpose of ADG442 is to allow for high precision thermocouple measurements.

    • In thermcouple input mode the thermocouple signal is switched…

  • RE: sigma delta ADC

    Hi,

        Thanks. We are trying to design an analog input module and we are planning to follow the CN-0209 design.I was asking whether I could replace the switches used in CN-0209(ADG1414,ADG442) and ADC AD7193 with a single ADC .

    Thanks and regards,

    Divya…

  • RE: CN0209: Universal AFE questions

    Hi Ching.

    First of all, the initial requeriments of my project:

         - 8 universal analog inputs (RTD, TC, 4-20, Voltage). 3 header pins.

         - Each channel can be configurated independently for RTD, TC ... measurement mode. Another choice if this option…
