• ADA4625-1 LTspice Model Offset Voltage


    when simulating ADA4625-1 configured as simple unity gain buffer in LTspice with single 5V supply (Vs- =0, Vs+=5V), I get a systematic DC offset of -45.406mV which is far beyond the max value in the datasheet (+/- 1mV max). Is there a problem with…

  • ADA4625-1 Crossover Distortion


    I am using the ADA4625-1 in a Digital to Analog Converter analog stage. I sometimes to like to use a current source to bias op amps into class a to reduce or eliminate crossover distortion. However, I noticed in the ada4625 datasheet that it says…

  • ADA4625-1 application without the -VS


    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?


  • ADA4625: what does IVR parameter means?


    I'm not sure what does the IVR parameter of the ADA4625-1 part means. 

    Is this the same as input common mode range parameter often used in datasheets? If so, and the Vcm = 1.5 as stated above the table, does it mean that the all the table is…

  • RE: what is the current noise density vs frequency for the ADA4625

    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…

  • AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)?


    I would like to inquire if it is possible to achieve precise frequency control with EVALZ - AD9531-1? I'm interested in generating a clock signal that is a multiple of femtosecond laser output pulse rate, which can be something close to 80…

  • Arduino UNO and ADXL345 getting 0 0 0 OR -1 -1 -1 outputs with SPI communication

    I have EVAL-ADXL345Z evaluation board from Analog Device hooked up to the Arduino UNO R3, the code complies and runs fine. At first I could still get…

  • RE: LTM4644-1 LT POWER CAD 3+1 MODEL,

    Hi kdeckstein, 

    Sorry I am unable to attach the example design tool file here. You can also access the LTM4644 3+1 tool (2 outputs) by going to the LTpowerCAD part search page, entering your input voltage range, selecting number of output rails to be 2…
