• ADG452: GND connections

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

     

    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

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

     

    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

    What are the Power Supply sequencing requirements for ADG452?

     

    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?

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

     

    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

    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…
