• 运放AD823A放大信号出现波形失真

    采用AD823AR运放做一个硅光电二极管两级放大电路，光源为脉冲激光，激光上升下降沿均为5ns，脉冲宽度为100us，设计运放电路原理图见图1，输出波形见图2，输出为什么和我预想的不同？

  • RE: AD823 LTspice simulation and data sheet disagree

    Hi Wayne,

    I'm sorry but we don't support that simulator. You can simulate your circuit in ADIsimPE powered by SIMetrix/SIMPLIS instead.

    There is nothing wrong with the model. You are using AD823A spice model and not of the AD823. The AD82…

  • RE: 最爱ADI放大器---AD823

    不错的分享，新设计可以用双通道、17 MHZ轨到轨FET输入放大器AD823A 替代AD823哦 http://www.analog.com/zh/all-operational-amplifiers-op-amps/operational-amplifiers-op-amps/ad823a/products/product.html

  • 运放测试条件

    AD823A Datasheet中，运放参数测试条件+Vs=5V，Rl=2Kohm TO 2.5V中的TO 2.5V是什么意思呢？还有运放参数的测试电路是什么样的啊？

  • RE: 有没有高输入阻抗低供电电压3V的JFET运放

    这个ADI的官网有，放大器JEFT，选型表3V：AD8244、AD823A、AD823、AD824

  • RE: AD7466 VIN drops issue

    Hi Jonathan,

    The AD8512 and the AD8620 are not pin-to-pin compatible with LTC2055 so I would not like to use them.

    I'll try to test with AD823A.

  • RE: AD822 Single-supply capability

    Hi Goz,

    One more question. According to the AD823A data sheet, its single supply voltage spec is 3V~36V.

    Do you have any plan to change this spec like AD822?

    Regards,

  • AD8606 bias vs. Input Common Mode

    Hi,

    Could you please provide the AD8606 bias current vs. the common mode for 5V?

    For example, here's figure 11 from the AD823A specs:

    Thanks for your help,

    Keep making these excellent OPAMPs!

  • RE: AD823 Open Loop Characteristics

    Hi Veerasamy,

    Yes, that looks odd. I'll check it with the product owner about this. AD823A has some improvement compare to AD823. Please check figure 18 of the DS for correct open-loop vs frequency.

    Regards,

  • ADP7118AUJZ-3.3-R7输出异常

    如上图，我把输入端的Vin和EN连接，输出的Vout和SS连接，给一款74HC4052D和4个AD823A供电，，，但是输出电压只有1.228V，而且ADP7118芯片发热量很大
