• ADA4700-1 gets hot

    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

    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

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


  • 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…

  • RE: 200V output from ADA4700-1?

    Hi Steven,

    I believe the ADA4700-1 itself can't go to 200 V output and adding a circuit after the op amp to boost its output can't be achieved without affecting some crucial parameters of the op amp.

    But i have forwarded your question to the…

  • 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


    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…

  • LTC6090 ADA4700 vOH vOL

    Presently we use the ADA4700 in a system whereby we can produce a very low current draw voltage (between +40 and -40V).  The ADA4700 is driven by a DAC to control the output.  

    When selecting the ADA4700, I took note that "rail to rail" is actually +- 2v…

  • How to choice the resistor power for ADA4700


    I'm working with the Amplifier ADA4700, I would like to make this below circuit. In the datasheet (see in this attach) I can see : 

    High output current drive: 30 mA thus The power at the terminal resistor is about 90 V (if Vin =10V) = 2.7W
