• About AD8599

    1. We are using the AD8599 at ± 15V.  When the room temperature is 25 ° C, device temperature  is 80 ° C. Are these normal?

  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…

  • AD8599 上电后发烫

    我用AD8599作ADC驱动电路,发现上电后,芯片烫手,但是输出波形正确,这个是什么问题呢?

  • AD8597/AD8599 CMRR MEASUREMENT

    I have to use an AD8599 and I tried to measure the CMRR with Vcc=+/-5V with
    -2V<Vcm<2V (as noted in the datasheet). The result is about 110bB (vs 120dB
    Min). I tried using conditions Vcc=+/-15V with -12.5V<Vcm<12.5V and it's the …
  • Input resistance of AD8597/AD8599

    What is the input resistance of the AD8597/AD8599?

     

    Due to being extremely low voltage noise devices, the AD8597/AD8599 input
    resistance is omitted from the datasheet (Rev. C 12/09), as these devices are
    typically used with impedances…
  • AD8599 voltage range - okay for phonostage replacement

    Hello,

    I want to upgrade the old opamp in my phonostage. The voltage 22+/- and would that be okay to use AD8599?

    Thank you

    Kind Regards

  • AD8599 CMRR measurement and mistakes on datasheet ?

    Hello my friends,

    I have to use an AD8599 and I tried to measure the CMRR with Vcc=+/-5V with -2V<Vcm<2V (as noted in the datasheet). The result is about 110bB (vs 120dB Min). I tried using conditions Vcc=+/-15V with -12.5V<Vcm<12.5V and it's the same…

  • Would the AD8599 suit the circuit of the phonostage?

    Hello,

    I was the AD8599 in both my Philips and Marantz CD players and love the sound.

    I have recently rebuilt my Technics SU-V9, some old capacitors gave out.

    Would the AD8599 suit this circuit in the phonostage section of the amplifier ?  17+/- voltage…

  • AD8599 input voltage range back-to-back protection diodes

    Hello,

    I have a question about the input voltage range.

    My circuit looks like:

    I have seen, there are ESD protection diodes between the positive and negative input.
