• OP470

    When I set the input to 0V i get 1.07V ath the output, (0.5V at terminal 3) !!

    Why i don't get 0V ?

    Thanks.

  • Noise performance comparison between the OP27 and OP470

    Good afternoon,

    Some background on why I care about this:  NASA GSFC launched a mission (ASTRO-H) a while back, and the front-end amplifier designs incorporated the OP470 in virtually all of the bias control.  However, the engineer at the time claimed…

  • OP470 : offset voltage fluctuation range by aging

    Hello,

    I have a question from our customer about aging of offset voltage of OP470GS.
    I guess that offset voltage of OP-Amp may be affected by supply voltages.
    And I think it will be categolized as quality information.
    Can I have the information about fluctuation…

  • Spice model of OP470  /  Problem with the input bias current

    Hi,

    While testing the model of the OP470 Op-Amp which we plan to use on a MIL PCB, I found a problem during the transient analysis.

    The datasheet of this component tells us that the input bias current should be around 10nA

    But in the simulations I…

  • OP470GSZ NC pin

    Hi all,


    Now, our customer will start to design the PCB.


    In the datasheet @ OP470 16-Lead SOIC Package,
    nc (8,9pin) : "NC = NO CONNECT".

    This mean, do not connect to other potential ? or no connect internal ?
    The nc pin is open, or connect to…

  • RE: quad opamp, isolation amplifier

    What are your supply rails? The LM747 will tolerate 22V supplies, which is more than most opamps will take.

    The AD8513, AD8674 and OP470 may be worth a look as they all have better performance. I don't know about Mil spec though.

  • RE: ad8138 fully differential amplifier as a transimpedance amplifier

    Hi Harry,

    You are right. With this bias current, the output offset is almost 0.7v with 100k.

    So do you have any amplifiers suggestion for the two classic TIAs?

    Before i was using op470. But it is too slow for this project.

    Thanks.

  • 运算放大器平衡电阻总损坏是什么原因造成的

    原理框图如下,如果用同一信号源,给几路通道一起输入信号,OP470前端1M平衡电阻总是失效,这是什么原因造成?信号源单独输入时不会失效。

     

  • Inquiry Stability of OP200A and OP470A under Incorrect power supply conditions.

    Dear.

    The two parts(OP200A, OP470) has been used in satellite system.

    The power supplied to the two parts within our design are +15VDC(+V pin) and -15VDC(-V pin) at power-on state.
    But, Due to some design error of the main power unit , in case of main…
