• RE: LTC1867 Technical Support

    1) Either ADC should work for your application. Both can do single-ended or differential

    2)If you run the ADC at only 1ksps or even 10ksps, either instrumentation amp should work

    3)AD5621 is only 12-bit, if that's ok

    4) you haven't said what op amp…

  • AD5622 Unexpected Output Voltages

    We have a product in which AD5621 was designed.  We cannot buy AD5621 at this time, and need to replenish our product stock.  I found AD5622 in distribution, and bought 10 of them

    for a trial in our product before committing to manufacture.  I wrote some…

  • RE: AD5641 evaluation

    Hi,

    Unfortunately, and as you have said, we do not have an evaluation board for this part. What you could do is:

    1. You can get another evaluation board of another part which has the same package as the AD5641. You may desolder the part then put on…
  • RE: high voltage current sink&source DAC

    Thanks for the hint with the AD5683R/AD5682R/AD5681R/AD5683, which are interestingly smaller than the AD5621 although both are LFCSP and the former has 8 instead of 6 pin (normally I would expect that same package type and more pins would mean bigger…

  • What amplifier would you recommend for a low power  4mA to 20 mA  current loop transmitter application?

    For low power application that requires RRIO and greater than 5V supply, I would recommend the AD8657 due to its low supply current of 22 uA per amplifier. The AD8657 is a 18V, micropower, rail-to-rail RRIO amplifier optimized for low power and wide operating…

  • RE: Can AD8318 CLPF pin be shorted to ground indefinately?

                          The part can’t handle the direct dc connection.  It can handle the ac swing. If you look at figure 5 on page 8, in the AD8318 datasheet, you see that 1.67 volts corresponds to an input power of ~ -53 dBm and the AD8318 will still try and close the loop…

  • RE: 有奖分享——最爱ADI放大器

    哈哈,不要说明嘛,看来你对偏流也是要求很高呀,ADI在这方面真的很强,失调1uV,偏流10pA,真很低了,后来记的北京郭工还推荐了一个ADA4528,失调更是低到0.3uV的程度。

    圣邦微的我也用过不少,GSM8554低失调、GMS321通用、GSM8054高速, 圣邦微的说他们的研发就是ADI的,不过产器真的跟ADI的很像,运放主要分三个系列,低失调、低功耗、高速。

    目前圣邦微还有两点不足:

    1:他们产品比较单一,运放都是5V供电以内的,没有超过5V的。

    2:把他们的产品与ADI的混入同一个系统…

  • Switching an RF Detector between Measurement Mode and Controller Mode

    Question: Is it possible to configure an RF Detector so that it can be switched between Measurement Mode and Controller Mode.

    Answer: The attached schematic shows one possible implementation where the RF detector can operate in Measurement Mode or…

  • RE: nanoDAC-What are nanoDACs?

    nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.

    nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…

  • nanoDAC - Which DACs should be used for open loop systems and which DACs should be used in closed loop systems?

    It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.

    In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…
