• LM399 quality issue

    I bought LM399H#PBF*200pcs and some failure happened like below picture, could anyone gave some advise while using LM399H#PBF.

    Thnak you.

  • ADC which can accept a 7V ref?

    Hello,

    Does ADI (or Linear) make any precision ADC's which can directly accept 7V as Vref?  I.e. is there a 24-bit or 32-bit ADC which can use a LM399 or LTZ1000 as an external reference?

    Thanks!
    Jason

  • RE: VREF LTZ1000 -55 +125

    I can't seem to find LM399 with operating temperature of -55DegC.

    you need to find older LM399. like those in HP 3457a. the low drift is fantastic due to the age.

    there is no click and order anywhere in this world for LTZ1000ACH or LTZ1000CH. you…

  • Temperature stabilized Instrumentation Amplifier.

    Looking for an Instrumentation amplifier that has a temperature stabilizing circuit. e.g. for LM399 reference, it has such a temperature stabilizing circuit inside. Can We find the same alike in an instrumentation amplifier? 

    If not,

    In the application…

  • RE: LM399AH

    Hi Koudjo,

    Currently we don't have the capability of doing this. I would suggest to just use a 7V voltage supply in series with arbitrary voltage supply with equation : V=(white(2e6*time)/110000) to simulate the RMS Noise

    In your application the deltaVz…

  • AD8672 is very easy to be damaged

    I already destroy more then 10 pcs AD8672 in my experiment.

    I just use it as a low noise unit gain buffer.

    Supply voltage are +/-12V

    IN+ is connected to the reference output from LM399.
    IN- and output is shorted to provide the negative supply voltage…
