• ADA4700-1

    what is the common mode voltage for ADA4700-1; and also please let us know any op-amp is having Vcm +/- 300V with single ended impedance of > 1M  ohms

  • Power supply for ADA4700-1

    Hi,

        Can I provide a single 100V power rail for ADA4700-1?

        THANKS.

    ADA4700-1
    Schematic below

    I am using the ADA4700-1 to provide +-40V DC with a 0 to +2.5V input.  The output of the ADA4700-1 drives a 47K ohm load (40v=<1ma).

    The ADA4700-1 is mounted to a DIP adapter board.  I am not able to attach the heat sink pad…

  • ADA4700-1 with large capacitive load

    One of potential applications of ADA4700-1 is a piezo driver, but solutions presented in the datasheet work up to 100nF only, while my piezo has 1.5uF. Could you suggest a circuit which would work fine in such a case? I need to work with the frequencies…

  • 200V output from ADA4700-1?

    I want to drive a MEMS device that is <10pF. We would like to be able to go 0 to +200V at 40KHz. Is there some way to boost the output voltage and keep the linearity?

  • ADA4700 - DAC-controlled dual polarity voltage source

    I've selected the ADA4700-1 in an application to drive a static charge upon a stainless steel plate (conductivity measuring instrument).  For this purpose I have two supply rails, one at +38V and the other at -38V.   The ADA4700-1 will be configured…

  • Characteristics ADA4700

    Hello,

    I'll working with ADA4700 Amplifier, can you confirm in the datasheet with this component, the current is about 30 mA, Output voltage +/-48V thus the power is about 2.88 W for this product ? I find 2 supply power and in the datasheet I can…

  • RE: ADA4700 Spice Model do not work "Missing node(s)"

    Hallo

    I use EAGLE to draw
