• AD5791 Buffer amp linearityuffer

    I want to achieve the best linearity possible from the AD5791B at low frequencies, below 1k Hz, but I'm concerned about the buffer amp performance.


    The AD8675 is recommended for the output buffer but it's minimum CMRR spec is only 114dB which equates…

  • ADG728 Analog MUX interference between channels

    Hello,

    i am struggling a problem on ADG728. I am trying to measure optical density over a photodiode array of 8 photodiodes(You can view the image i attached). My problem started with my realization of false readings over channels. When i connect the…

  • RE: Driving analog data convertor AD7823 with an op-amp

    Hello Eyal,

    On the question of using a single-ended vs. a differential-output amplifier, it generally depends on the level of precision you are trying to obtain. Since the AD7823 is an 8-bit ADC, it's LSB size with a  1.2V reference, one-half of…

  • RE: 有奖分享——最爱ADI放大器

    使用了很多ADI的模拟器件,主要设计仪器仪表类产品。

    AD8571:超低失调电压运算放大器, 使用这个运行主要因为两点:

         1:超低的失调电压,1uV,什么概念,就是一点点热电偶效应你都要考虑一下,不然你就浪费了AD8571的正能量了。用来测量1A电流时,只需要串个0.01R的电阻就能非常精确的使ADC达到60DB的动态范围。

         2:超低的偏置电流,当你要测试10nA的电流时,你就会知道这个是有多重要了。

    AD8331:数字可控型仪表放大器,这个放大器由两部分组成,一个仪表放大器,一个普通运放…

  • AD8220 Vref

    Hello fellow engineers and enthusiasts,

    I've been using this instrumentation amplifiers for a few months now, and I absolutely love it for its robustness and pricing. I'm about to do a design that will need to adjust the offset, and the AD8220 offers…

  • Noise optimizing AD8599 &&

    Good day,

    I have a task to optimize noise in BW 10Hz - 10kHz.

    Voltage gain shall be around 20..50. OA connected directly to source of signal,

    which has impedance 1kOm DC and 50Om AC. OA connected to middle point of R1/R2 divider,

    where R1 connected…

  • AD8616 Supply Voltage

    Hi,

    I'm still relatively inexperienced with circuit design and I am wondering if I am misunderstanding something fundamental about this particular op amp. The AD8615 series is a single supply op amp, but one of the listed application is photodiode preamplification…

  • RE: Please recommend some buffers or drivers with high current driving capacity

    Hi Vic,

    Here is an Excel sheet with devices which have > 100mA output current sorted from high to low current for your review:
