• AD8610: Short circuit current - driving the AD7667

    Does the output buffer of AD8610 opamp has short current limitting circuits?
    What its characteristics?
    Can the AD8610 drive AD7667 ADC?

     

    AD8610 does have short circuit protection, limiting the current to typically
    65-100mA. The absolute…
  • Ad8610 Spice model

    Is there an issue with the AD8610 spice model?

    When I compare the ADA4610, AD8625 and AD8610, the output (Vout3) of the 8610 is heavily dependent on the input resistor R14.

    For 1K or higher the output goes to the -rail.

    This occurs when using +- 10V…

  • SPICE Model for AD8610 does not work

    I'm using the AD8610 in a simple buffer application. AD8627 and ADA4622 are working as expected but in the prototype i am bound to the AD8610. See the part of the simulation below.

    Followup: I tried also to eliminate R1, R2, C1 and C2, same resu…

  • AD8610 supply current

    Hi!

    I am trying to use an AD8610 opamp in an active loop filter for a PLL, but after applying a 25V supply voltage my power supply indicates 25mA of supply current instead of the 3-4mA described in the datasheet. How is it possible? The PLL was either…

  • AD8610 unused offset pins

    Hello,

    I want to take the AD8610. But I dont want to use the offset pins.

    Should I leave the pins open?

    And I want to connect the not connected pin with GND. I hope that I get more possibilities with the layout…
  • Input Offset Voltage Adjustment AD8610?

    Hello ,

    I thing about nulling Input Offset Voltage using digital potenciometer.

    How calculate potenciometer value for nulling input offset AD8610?

    Or different way, how nulling Input Offset over nulling pin, with DAC?

  • Issues using an asymmetrical supply voltage

    I’m using this component [AD8610] in a PLL design with +12/-5V supply. Now I
    seen that
    it works fine (despite the specs) also with +12 and 0V.
    I need some info about  possible problems I’ll have  using the component in
    this way (the…

  • RE: 弱信号检测中,设计i\v转换电路中,选用pA级别的偏置电流,高带宽的运放,仿真时,发现偏置电流随着频率变化而变化,这与逻辑不符,想问下为什么

    我的实际电路就如我仿真所示,ad8610芯片我采用±13v供电,输入信号我本质上为了测量电容和电阻的一个并联等效模型,我现在仿真就是为了看这个ad8610能否满足我的输出要求,正如我图中所示,我的输入为vpp为2v的正弦信号,频率我扫频从700k到1.1Mhz,输出的电压就是不满足反相输入运放的放大规律,我通过仿真去测量它的反相输入端偏置电流,ad8610的输入偏置电流为pA级别,但是正如我扫频结果所示1.1Mhz时,其反相输入端偏置电流达到了65微安
