• 最爱ADI放大器-AD8607

    单就运放而言,在这几家最大的模拟厂家里,ADI的运放种类是最全的,每次总是能选到最合适的。

    我做的直流精密测量方面的比较多,我选用AD8607这款。近几年,在做水质分析仪器,只要是直流放大的应用,都上AD8607毫不犹豫,每个项目都很好的满足要求。

    我大概总结了一下,AD8607有这么十大优点:

    1. 低失调,低温漂

    2. 单位增益稳定(可用于跟随器)

    3. 输入输出都能轨对轨,R-R Input,R-R Output

    4. 功耗低,但输出驱动能力还强

    5. 低压,单电源(现在这可能不算优势了…

  • 我选用了一款AD8607的芯片,想仿真,用什么软件呢

    TI公司有一款仿真软件叫TINA,可以很方便的仿真TI公司的芯片。那么请问ADI公司是否也有这样的仿真工具呢,我想仿真AD8607

  • RE: AD8541 AD8542 AD8544 noise (low frequency)

    I was thinking about AD8539, but AD8607 also looks good. I will take this op-amp for RLD circuit.

    Thank you Harry!

  • Simultaneous measurement of pH and ORP

    Hello, I use CN0326 to measure pH (mV), the result is very good, but I want to measure and add ORP parameters on the same circuit at the same time. i changed Opamp AD8606 (1 channel) to AD8607 (2 channel). Then connect two pH and ORP sensors simultaneously…

  • Max Input Current

    I am using the AD8607, and occasionally there is a 6mA current fllowing into the input pins. Is this going to pose a problem? I can’t find any information on the maximum input current limit on the data sheet.

  • RE: Using The ADA4177-2 as a buffer, outputs don't exactly follow inputs

    I'm surprised it is doing anything. 

    --  You need at least 5V across the part to wake it up

    --  It is not RR input;  you need to stay at least 1.5V away from either rail.

    Try an ADA4084-2 or an ADA4528-2

    For the LMC662,, you could also look at:

    ADA4691…

  • RE: Need help with common mode noise

    Hi Fausto Bartra,

    Based on the details you have mentioned, I suspect you're experiencing 1/f noise since your bandwidth is very small. You can try to look at amplifiers with lower 1/f noise if AD8607's 1/f noise performance is significant compared to…

  • RE: 分享您最中意的ADI资料,赢跨年好礼

    已经做过好几个项目了,感谢AD8607,非常出色的应用在直流放大方面。优点有:功耗低,但输出驱动能力强;共模电压输入范围无限制;很高的共模抑制比,电源抑制比;极低的输入偏置电流Ib。

    Riscy,

      AD822 came out in 1993, close enough to 1995.....

    Our IEEE subscription only covers in house use, so I can't send it to you, but the part was written

    up  by Close and Santos.

      Without knowing your highest signal frequency, source impedance…

  • AD8232's IAOUT has some random noise

    I bought AD8232 EVAL and checked ECG signal under the following configuration.

    <Configuration>

    3 electrode connection

    DC leads off detection

    FR disable

    During measuring ECG signal on IAOUT and OP AMP OUT, there are random noise on both signals…
