  • AD8129: Higher gain

    Q 

    The customer wants to use the AD8129. They need a  gain=250. in the datasheet
    always there talk of maxgain=10 and the resistors for feedback are given only
    for maxgain of 10 (page 12/Datasheet). Are there any limitations for higher
    gains higher…

  • AD8129 AD8130: output impedance in power-down mode

    Q 

    A customer asked why we specify the output impedance of AD8129/30 in power-down
    mode as 10pF in the datasheet? Does that mean in power-down mode, the output
    impedance is very high for DC and will get lower as the frequency increasing?

  • RE: AD8129/AD8130 Power Sequence

    Hi Chris,

    I want to apologize for the delay in getting back to you.

    Is it at all possible for you to remove the delay on the negative side to see if the issue goes away?

    If not, can you add a larger cap on the positive side to make the 400ms delay much…

  • AD8129 output supply voltage

    I designed a differential current-to-voltage output circuit with AD8129, but now the circuit output voltage is always 12V(positive supply voltage).

    Input 1:differential current 20mA (IN+ minus IN-)

    Input 1:differential current 10mA (IN+ minus IN-)

    out…

  • AD8129 noise improvement

    I used AD8129 as a differential amplifier in my project. 

    My specifications are meet the criteria except for NOISE.

    Is there any way to improve the noise for AD8129?

    Please teach me how to improve the noise of AD8129.

  • MTTF-reliability data for XFCB (or FastFET?) technology (AD8065, AD8038) and AD8129 (unknown technology)

    Hello, thanks for your time

    I need the MTTF--reliability data for the chips

    1) AD8065 and  AD8038 [ XFCB (or FastFET?) technology] 

        I have searched the data in https://www.analog.com/en/about-adi/quality-reliability/reliability-data/wafer-fabrication…
