• AD8605 SPICE Model Input Capacitance

    AD8605 Specifies CCOM as 8.8pF and CDIFF as 2.6pF yet the SPICE model defines only:

    C1 14 16 0.6E-12
    C2 17 18 0.6E-12

    which I think are the CCOM values. In order to simulate these correctly, is it best to simply add the components externally.


  • Unexpected AD8605 filter behavior in LTspice

    I'm using LTspice to simulate a LPF using the AD8605. I'm expecting this circuit to attenuate high frequency signals but the output I'm getting is attenuation at any frequency, more so at low frequencies. As a sanity check I've made sure I have…

  • AD8605

    Can this be used as a comparator? and how? Thanks

  • how to test the AD8605 as TIA (I to V) design using current source?


    I am trying to test the Trans-impedance amplifier design using AD8605 for the photo-diode application circuit.

    currently i am using an NI 9265 module to generate current source up to 20mA in my setup 

    below is my circuit:


    when i try to set the…

    Hello, is AD8605 a current-feedback op amp? I couldn't find this information on data sheet.

    Thank you.

  • AD8605 input protection


    Does the AD8605 have a protection against voltages below 0V ?

    I can see in the datasheet (p 16) that there is a protection against overvoltage. It says that if the voltage is 0.5V higher than Vcc supply, a current limiting resistor should be added…

  • AD8605 4 level filter can't work

    Hello, I design a 4 level filter in accordance with the online design wizard of ADI, as follows, but, it finds that the second level is output 0V. Why?  how to adjust and test?


    Single power supply 4V;

    VREF = 2V;

    The first stage output 5mV…
