• RE: AD8279 difference amplifier - Vref pin

    Hi Jimmy, 

    The AD8279 reference pin has a relatively high impedance, and it should not be a problem for the OP1177 to drive several of these pins. What is your reference voltage and how many AD8279s are you planning on using?

    Thanks, 

    Kris

  • I have a problem with AD8279. Please help.

    Hallo.

    The first time I have used AD8279 was a project for railroad generator control system. I have made all analog data convertion from current, voltage and thermo sensors to ADC of microcontroller on it. And was very glad because today I have about…

  • RE: PSpice model of AD8273 amplifier

    Hi abhijitpethkar,

    I'm sorry for the delay in answering.

    If this is still a concern, I know of one functional equivalent that has a spice model: AD8279. But the AC specifications are very different. I'll move this message to the Differential Amplifiers…

  • RE: How do I design an attenuator using OpAmp?

    Hi Naji,

    In addition to the considerations that Harry has given, you can also take a look at our AD8275, which is a G=0.2 difference amplifier. With a 0-10V input, it will give you a 0-2V output (or you can level-shift the output) so it won't give you…
