• ADG452: GND connections

    Q 

    Where should I tie GND connection, to digital or analogue ground?

     

    A 

    As long as there is some interconnection somewhere in the system between the
    Analog GND and Digital GND, the bipolar switches can function with VL connected
    to …

  • Status of ADG452

    I noticed the Product Status shows Production, but there is a recommendation just below that states NEW DESIGNS consider ADG1412 or ADG5412

    Is there going to be continued production of the ADG452?

    We need a life of at least 7 years, perhaps more so…

  • ADG452: VL = 15V possible not not recommendable

    Q 

    How do the voltage levels change when I use VL=15V, which does not violates the
    abs max ratings?

     

    A 

    It is not recommended to use +15V on the VL pin. Using this level will change
    the threshold voltages and we do not have any data to say…

  • Power Supply sequencing requirements for ADG451, ADG452, ADG453

    Q 

    What are the Power Supply sequencing requirements for ADG452?

     

    A 

    You should not power up VL before VDD or you will be exceeding the
    absolute max ratings for the part (VL to GND  = −0.3 V to VDD + 0.3 V) and will
    result in part failure,…

  • Can the ADG452 be powered from a single 24V supply and 3.3V digital supply?

    Q 

    Can the ADG452 be powered from a single 24V supply and 3.3V digital supply?

     

    A 

    Yes the ADG452 can be powered from a single 24V supply and logic power supply
    VL can be 3.3V.
    Note you should not power up VL before VDD or you will be exceeding…

  • ADG453: Power Up Sequence

    Q 

    Why some microcircuits ADG452 and ADG453, at submission supply voltage Vdd = +
    15 V, Vss =-15 V, VL = + 5 V start to be heated up strongly, the current of
    consumption up to several tens ma increases, at changeover by other copies of
    …

  • Video switch - which chip to use?

    Please excuse my very basic/non-existent electronics knowledge.

    I am trying to build an audio/video switch which supports analogue RGBHV video up to 480p/60 (640x480) resolution, to switch a possibly large number of input devices (maybe up to 10). This…
