• Opamp AD8692 stability issue.

    I have an amplifier AD8692 used for voltage sensing with opto coupler for isolation. it is quite unstable in the whole range of input voltage. 

    i have tried to simulate it in ltspice and its quite stable. maybe the model is not so perfectly represented…

    I can't find them for AD8692 opamp and ADCMP608 comparator. No special footprints, I just wanted to double-check.

  • RE: ADA4530-1 Die level option

    Hi Mika,

    We currently don't have ADA4530-1 in a die level and I'm  not sure if we will have in the near near future. However, i found these few devices with 1pA typical bias current operational amplifiers in die/chipscale package. We have AD8691…

      What does TRRS mean??

      What is your highest signal frequency?

      Depending on whether you need to go to DC or not and can AC couple, you could use op amps

    that have millivolts of offset, rather than <100 uV which drives up the price.


  • RE: CN0276 EXC filter design

    Hi firman,

    Figure 12 is the phase shift between the AD2S1210 EXC and SIN pins which shows how the noise from EXC pins of AD2S1210 was improved.  This is because of the amplifiers which acts as an active filter found at the resolver excitation(which uses…

  • AD8348 with added baseband gain

    I say you chaps...

    I've added two LNA (MAX2634 - sorry!) and active filters with gain at baseband. It's a tough one to keep stable!

    A SPICE model for the AD8348 would have been nice, to check the bias. I have built it, it does work, -100dBm…

    Thank you for a thorough explanation.

    I have looked further at your catalog of op-amps. Since I am designing a portable unit, I examined the following, with 5 V supply:

    AD8605/AD8606/AD8608, AD8691/AD8692/AD8694, AD8655/AD8656, and the ADA4075-2.
