• RE: ADG741: Is the switch is closed or open in the event of no power supply?

    Hi cklooi3,

    The state of the ADG741 without power cannot be guaranteed. ADI does provide a part that guarantees switches are off with no power supply present. This part, the ADG4612/13 can be found at the link below.

  • CMOS Switch Modeling

    Hi,

    I'm performing a Spice simulation including a switch for which no Spice model is provided. To evaluate the transfere funtion of my circuit I'm modeling the switch by a simplyfied PI - network. So I use the on-resistance and the capacitances, stated…

  • Are ADG1408 channels isolated from ground?

    Hello,
    I've got a problem trying to use an ADG1408.
    I need to switch an external circuit on different resistors, but this circuit must be isolated from the ground and power supply.

    I tried using an ADG1408 but channels seems to be connected to VDD/GND…

  • RE: Re: Mux ADG1409

    Hi TheresaC,

    Here my schematic.

    Is a switched measuring system for 0-10V, 0-20mA and PT100. My requirement is that each input can be configurated as a V, mA or PT100. Only one input is measured at time. For this I want to use the ADG4612, for input…

  • RE: ADG858: Switch state in device off state.

    Hi,

    When there is no VDD present, there can be no guarantee to what the state of the switch will be.

    If you need the switch to be in a guaranteed state when there is no supply present then let me recommend the ADG4612. In this part the switches are…

  • RE: ADG824 / ADG884 switch impedances with Vdd=0

    Hi Mike,

    Yes, you are correct. When Vdd=0V the switches are turned off of in high impedance. However, when an audio signals are present and Vdd = 0V, you are risking the overvoltage event.

    Let me explain it this way, the source and drain terminals have…

  • RE: ADG 5412 switch resistance when part not powered

    Hello Robert,

    There is no specification for resistance when the part is unpowered because applying a signal while the switch is unpowered is operating it above the absolute maximum ratings and is likely to damage it.

    The signal should not go above the…

  • RE: Bipolar signals on a switch with single supply

    If the analog inputs on the source or drain pins go below the substrate (Gnd) when the part operates from a single supply, internal ESD protection diodes will start to turn on.  When this occurs you can expect to see distortion or clipping of the ON channel…

  • RE: USB Protection IC

    Hello Huang,

    The ADG4612/ADG4613 are parts with overvoltage protection and can operate with a 5V single supply.

    The bandwidth of these parts may not suit your application though. The low voltage switches in our portfolio that can support USB2.0 do not…
