• ADG884 Overvoltage

    Why does the ADG884 switch get stuck at a certain voltage when the input
    voltage exceeds the maximum


    Under or overvoltage spikes can trigger parasitics in the part that cause
    new paths to be created in the silicon, which…
  • ADG884: Bandwidth simulation

    I´m using the spice model of the ADG884. In the datasheet the -3dB Bandwidth is
    18MHz. In the simulation the result is about 1.7GHz. Is the analog bandwidth of
    the signal chain not contained in the Spice model?


    The SPICE Model of ADG884…
  • ADG884 switch Bi-Directional..?


    We are using the ADG884 switch in an audio application.

    The end device has one mono audio input connector, and the ADG884 is being used to select whether it is in input or output mode - see image below.

    Question --- are the audio channels in the…


    I'm DFAE in Japan. My customer asked me what are meanings of ABSOLUTE MAXIMUM RATINGS in the datasheet of ADG884.

    ABSOLUTE MAXIMUM RATINGS of ADG884 are described as follows.

    Analog Inputs,(1) Digital Inputs −0.3 V to VDD + 0.3 V or 30 mA (whichever…

  • ADG884 Location at Audio Amplifier Output


    We are using ADG884 for switching audio signal from one channel to another as shown in the image below.

    In the datasheet of ADG884 it is specified "Analog Signal Range is 0 to Vdd". This raised a doubt in our mind that what should be its location…

  • ADG884 Threshold voltage on IN1/IN2

    I selected the ADG884 to switch analog signals which have a 0-5V range (hence I'm powering it from the same 5V rail) using a logic signal that has a minimum high voltage of 2.5V as the ADG884 data sheet says that when powered from 5V the digital inputs…

  • ADG884 channel mismatch over voltage and temperature

    My customer is using the ADI ADG884, but is having issues with the channel mismatch over voltage and temperature.  He needs a

    a “low On resistance” analog switch that operates at 5V; which also has milli-ohm channel matching.

    Is there a part that is…

  • ADG824 / ADG884 switch impedances with Vdd=0


    We are considering using either the ADG824 or the ADG884 dual SPDT analog switches, however our application requires the switch analog terminals to be in a high-Z state with the device Vdd=0 V as audio signals are still likely to be present even…

  • About an ADG884 power supply off state

    It is the question from our customer.

    Is SW open in power supply OFF?

    I think that I become open (high impedance), how about?



  • ADG884 switching issue at 80-85 Deg. C operating temperature.

    ADG884 switching issue at 80-85 Deg. C operating temperature.

    We are using ADG884 in data acquisition system. 

    ADG884 is multiplexing two difference voltage followed by instrumentation amplifier and Delta sigma ADC. The 1st voltage is 25~50mV and 2nd…
