• 关于5V运放AD8651电路的设计问题

    如下图，使用下图的话能够实现图中的输出？

    vi 相对 SIGREG 的输出为 0-5v。系统电压为24v，如果要实现对地电压为0-5V的缓冲输出，是必须用高电压运放来实现么

    请问 AD8651和AD8652具体在性能上有什么区别，哪款性能更优

  • RE: Transient simulation using AD8561.cir file on LTSPICE: Latch failure

    Hi Julien,

    I concur with you that something strange is going on with the AD8561 Latch functionality. I also see the latch giving up after a certain amount of time!

    Here are my simulation files for reference:

  • RE: AD8601 unity gain buffer

    I got it, thanks. Ad8651 seems to be proper. I need to use high resistance value resistors with the opamp and ad8651 seems to be a fit for that too.

  • RE: composite amplifier

    Hi Sampath,

    I suggest you can use the AD8651/AD8652 part. AD8651/AD8652 has a bandwidth of 50 MHz at 5V supply, has low noise density of 4.5 nV/√Hz at 100 kHz, has a typical offset voltage of 100 uV and slew rate of 41 V/μs. You can download its datasheet…

  • RE: AD8655 cannot simulate current noise

    Hi Harry ,

    Thank you for the information with regards to this issue .

    AD8651 has a simulation model have taken this as a reference .

    Thanking you

    With best regards and wishes

  • I-V converter for PMT

    Hi,

    My name is charles.

    I'd already used the the high speed video amp(AD811 and AD8057)and ultra low input current offset amp(AD549) respectively in my simple I-V converter circuit to get a singnal from PMT(2uA max) with Rf(100Mohm).

  • RE: 使用ADA4897-1出现大幅失调电压 ，怎么办？

    Jason，

     

    为了获得增益10，乘以400kHz，乘以10-20裕量，我会挑选一个增益带宽为40-80 MHz的运算放大器。

    关于噪声，查看AN-940可获取低电压噪声运算放大器表以及低电流噪声

    运算放大器表。 由于在大于五的噪声增益下运行，也可以使用非完全补偿放大器

    。 因此ADA4637-1、ADA4898-1、AD8651、OP37、AD8022或ADA4897-1将都是不错的选择。

    关于您提到的源阻抗，我会关注低电压噪声。
