• 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?

  • 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: 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.

    Regards,

  • 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,

  • 运算放大器的THD+N参数应该怎样用呢?

    大家好,我想给信号采集电路加一级缓冲(同向输入,单位增益放大),需要供电+-12V,压摆率至少20V/us(越高越好)以上。需要缓冲的信号为2MHz以下的单频信号,由于要考虑低功耗并且驱动容性负载,准备评估的双运放芯片有:

    ADA4622-2(665uA),ADA4610-2(1.6mA),AD823A(5.1mA),AD8620(3.5mA)以及AD8066(7.6mA)

    综合来看ADA8620最优,但是价钱太贵了。准备用ADA4610,但是压摆率又有点低。

    我看了这几个芯片的THD+N指标…

  • 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

  • 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…

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

  • 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: 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!
