  • ADA4625-1 application without the -VS

    Tzachi
    Tzachi

    hi

    i have used the wizards help to create a design using the ADA4625-1

    my question is - do not have an option for -VS on my board

    if i ground this pin would i get only half the amplification?

    how else would this effect my design?

    thanks

    Hi Javier,

    Depending on your filter requirements, you can also try the latest ADA4625-1 18MHz GBP, which is perfect for PLL applications. For your +20V (pos supply) and 0V (neg supply), ADA4625-1 will have IVR of +16.5 to 0V.

    Regards,

    Kaung

    Is there any update on this topic. I too am looking for info on the current noise at low frequency. I intend to use ADA4625-1 for a unity gain buffer following a passive R-C filter ~1 MOhm + 20 uF (CDE #935C1W20K-F) and would like to estimate the noise…

    Hi, 

    The spice model that is on the OP27 product page can still be imported into ADS. It must be noted, though, that we have not tested this on Keysight ADS. We do our best to model them with various simulators in mind, so I would think this should still…

    Hi Guruditya, 

    The OP27 is not a rail-to-rail input and output part, unlike the OP184. With a single 15V supply, you will get very little input and output range from the amplifier, and this is probably not the best choice for this application. 

    You can…

    Today’s blog is about a new amplifier from Analog Devices. Amplifiers are pretty special to ADI since they were the first products we ever made, back in 1965. This is reflected in our company logo which features a tilted triangle - the schematic symbol…

    Hi Anh,

    We've noticed that voltage feedback op amps are sometimes easier to implement active loops with phase frequency detectors like the HMC439 and HMC3716 that output voltage pulses. Next, you need to decide whether or not you want (or need) an op…

    Hi Gideon,

    I moved this thread to the "CrossCore Embedded Studio and Add-ins" forum as it appears a tools related issue.

    I suspect that one of the automatic file attributes is being replaced by a macro define in the compiler generated assembly…
