• Hi, A question about the difference between the 524 and 624

    My question is what is the main difference m between the AD524 and AD624?

    ...and are there any lower cost alternatives to the 524? Like 8XXX series?

    My application is for bridge amplification.

    Thanks

  • Current source "without" temp drift

    Hi,

    I'd like to make a High precision current source with excellent temp drift (10 to the power of -6 or at best better than that). Current: about 0.5 Ampere

    At the moment I have an AD624 combined with a Vishay resistor in mind. How can I go…

  • RE: Spice model of AD524 to simulate in ORCAD

    Hello Satish,

    Unfortunately, we do not have a model for the AD524. However, there may be a few alternatives.

    For functionality, you can try to simulate with the AD624 model. The gain equations are not the same. Depending on your circuit, you may need…

  • AD7192 source impedance

    The datasheet of the AD7192 states that you could use the inputs both buffered as unbuffered.

    As I have a sensor (which will be used in a quarter wheatstone bridge configuration) with a nominal resistance of several kOhm (could be 30 kOhm) I was wondering…

    毕业不久,跑南方打工,设计中忽发奇想,用八组继电器+电阻做256级的程控运放,用的是 AD624 仪表放大器,效果居然不错,老板立马提级别、涨人工、改善住宿,真开心。只是手头继电器比较大,一个继电器比火柴盒差不多,做出来的实验板超级大,老板下命令减小尺寸。手快的兄弟重新垒板,换指头大的信号继电器,加50Hz工频信号,上电一试,傻眼了,程控功能没问题,但输出畸变严重,老板也跑来加班排查问题,七八号人马一通乱,换新板、割板、飞线、换通道、换信号不已,通宵天亮了还没解决问题,拿大板子出来一试,没问题。休息一天…

  • AD621: PSRR

    Q

    We have an AD621 measuring the voltage drop across a 2.5R sense resistor.
    We are measuring 78uV of noise at the output of the AD621 with x10 gain. I have
    taken the inputs 2,3 out of circuit and directly shorted them. The noise is
    still there.
    The…
