    I just received the product and it looks like this, but the appearance of the data sheet is different from mine. Is it correct?  Thank you~~ 

  • Initial configuration for ADL5240 Evaluation kit


     We are using ADL5240 evaluation kit to verify VGA performance/functionality. 

     What is the initial configuration or steps need to be followed to verify variation in signal power as we vary attenuation  through GUI application? 

    I am feeding input to AMP…

  • ADL5240 - EVAL BOARD

    Hi all,

    My research team and I bought the ADL5240 EVAL Board (ADL5240-EVALZ). We are unable to use the software with the USB. We are facing this error (sorry for if the screenshot is in french, the main computer we are using is in French by default):

  • ADL5240 internal digital attenuator switching time


    What is the switching time of the internal digital attenuator of ADL5240.

    Also please explain what the gain settling time in below figure from datasheet and I am not able to understand the X scale.

  • ADL5240

    Hi All,

    I am using ADL5240 as a variable gain amplifier in DSA_IN/AMP_OUT configuration. I wanted to know what would happen if i dont put the 50 ohm load resistance at the load. (My output trace is very short) and I am driving a cap load of 32pF at 5…

  • RE: ADL5240 LOGIC input ratings

    Exercising the digital logic on the ADL5240 without the power supply active can damage the part.

    In general, for logic inputs and most other I/Os on most products, there’s ESD protection to the supplies. If one forward biases one of these pins for an…
