• ADG508A: Enquiry for product specification



    Information enquires:
    1.) Thermal Resistance from Junction to case (Theta Jc),
    2.) Maximum junction temperature


    Pls kindly note that I would only need Theta Jc and not Theta
    Ja(Junction-to-air).

     

    105˚C is the max case temperature for…

  • What is the effect on ADG508A about a floating input?

    Hi,

    I'm working with two ADG508AKR connected to an ADC (AD7880CR) through an OP297GS.

    On one of the multiplexer, I have an input which is an option to my design. When this option is not installed, the input is floating.

    We are reading each channels…

  • Need Maximum Junction Temperature of ADG508A

    Please provide Maximum Junction temperature of ADG508. The value is not available in datasheet. Only Thermal resistance is provided.

  • ADG508A  function with low supply voltage

    Hi,

    The electrical specifications of ADG508A is guaranteed  with 10.8V to 16.5V.

    When ADG508A is used with 5V single power supply, is it guaranteed the attached specifications?

    And regarding the function of ADG508, is there anything to be concerned…

  • ADG508_thetaJC and maximumTJ

    please provide ADG508_thetaJC and maximumTJ

     

    105˚C is the max case temperature for the ADG508AKR. I have calculated it using
    a TJ of 125C.
    (Pd = 470mW; Rjc =42.9 °C/W; Tj = 125°C) for Tc = Tj - Pd x Rjc = 104.79

  • ADG508 ADG509_digital control voltage range

    If the ADG509F works with +/-20V power supply, is it OK to use 20V logic input
    for the EN and A1,A2,A3?

     

    The ADG508F will work with +/-20V supplies and under these conditions the
    digital inputs can go between 0V and 20V. While we know the part…

  • RE: Thermal resistance of ADG508

    Hi,

    The theta J-A (Junction to Ambient) for the ADG508A packages are as follows:

    16 lead SOIC = 124.9 degC/W

    16 lead PDIP = 103.3 degC/W

    20 lead PLCC = 89.4 degC/W

  • RE: MUX damage, o/p short to +Ve supply

    Hi Jatin,

    The ADG508A or ADG1408 switch inputs cannot exceed the power supply rails so there is a risk of damage if the input voltage is higher than expected or if the power supply turns off while switch inputs are still present. The abs max ratings…
