Hi,
Please refer the attachment for schematic.
I am working on multi channel Data acquisition system. Each channel is sampled and quantized in 25 us.
AD7631, 18 Bit ADC, is used in this design. As per the information given in the ADC datasheet, a RF…
资料拓展
AD8271是一款低失真、精密差动放大器，内部具有增益设置电阻。它可以配置为高性能差动放大器，增益为½、1或2，而无需外部器件。它也可以提供40种以上的单端配置，增益范围为−2至+3。
AD8271采用10引脚MSOP封装。该器件可以采用单电源或双电源供电，最大电源电流仅为2.6 mA。额定温度范围为−40°C至+85°C工业温度范围，并且完全符合RoHS标准。
原来如此，十分感谢！还有个问题想请教一下，就是采用这种方波调制光源后，光电二极管接收到的信号是不是应该变成交流信号了？ADG733和AD8271构成的同步检波器为什么只允许与LED时钟同步的信号通过呢？这块原理有点不明白
Hi,
Thank you for your recommandations.
Actually i would like to you use AD8274 or AD8271 difference amplifier.
Should i use buffer amplifier (like LT1818) at inputs?
Hi F. Buonomo,
Please check this great article for the different current sense topologies and some information on the consideration and how to use them. I think the one shown on Figure 1 d is a good approach.
With regards to the parts, please have a look…
Hello Bdolf,
You have pointed out many valid points. Instrumentation amplifiers like AD8429 don't lend themselves very well to build fast and precise PGIAs because of the problems you mention in your post, being the parasitics added to the RG pins one…
Hi Peter,
I talked to an in amp designer about this question. He mentioned that it might be possible that the short circuit current limit is engaging, although he would be surprised. The short circuit current limit is something we spec as a typical number…
这是第二篇有关分光光度计应用的文章。在第一篇文章中——ADI双光束分光光度计解决方案（http://www.analog.com/media/cn/technical-documentation/apm-pdf/adi-dbs-solutions_cn.pdf），我们讨论了应用、工作原理、电路架构和设计考虑因素。本文将介绍ADI公司的相关新演示系统和产品。
