• AD823 schematics review

    I have a problem with ad823 amplifier in my project. The impedance to inverting
    input is high. The Output voltage of the amplifier in the pcb board is not
    acting as a simulation . In the simulation I get 2 volts output  Nation profile
  • ad823: Rload influence of the GBP

    I'd like to use the OPAMP AD823 in a closed loop as amplifier between 0 and
    100kHz (gain is 20 or 100).
    The datasheet Rev.0 fig.11 shows the dependence of open loop gain vs. output
    voltage (parameter=load resistor).
    The question…

  • RE: 最爱ADI放大器---AD823

    我看到官方网站说 ADA4622-2 可以替代AD823A,拥有更低的噪声和更快的速度。可是我看了一遍两个芯片的手册,并不是这样的呀!

  • AD823 Open Loop Characteristics

    Hi,

    I am performing Stability analysis for a circuit with AD823 Opamp. I was checking Open Loop Gain parameters of the OPAMP and I referred Figure 14 of the datasheet.

    In the figure, the frequency response is plotted from 100Hz. It can be seen that…

  • AD823AR: ESD protection

    Can you give me some details of the input ESD protection system employed on the
    AD823AR.

     

    The AD823 uses parasitic Schottky diodes to divert the energy due to an ESD
    hit.

    These ESD diodes can protect the IC from ESD hits up to…
  • AD776

    AD7766 采用单通道架构,前端加AD823做跟随,输入电压为0-2.5V. ODR=128khz. AD7766由于内置数字滤波电源,首次输出数据为74/ODR. 约为400+us.  但第二次输出数据是否能支持1/ODR?  目前异常现象是: 1.ADC 输入数据V1后,延时400us后,读取到了正确数据。后面以100us 读取数据均OK. 2. 当ADC输入数据更改为V2后, 延时100us 后,读取数据却为V1, 延时接近400us后,读到正确的数据V2.  疑问,当输入数据发生变化时,第二次输出数据也需要74…
