• RE: AD7982_Eval Board  not Correct?

    Thank you, Lloben.

    When I short input of AD7982 evaluation board, I found reading is quite near 131072 (ideal case). My question is: Is AD7982 auto-calibrated with offset already? Should we calibrate for offset as short is not easy to implement when…

  • AD7982 Simulation Tool

    Hi,

    May I check if there is any simulation tool available for AD7982?

    I have tried Visual Analog and Virtual Eval Tool – Beta but both tools do not have AD7982 library.

  • Query AD7982

    Hello Friends,

     

    I am using three AD7982 on my board and are interfaced with PIC24HJ256GP610A controller. The mode selected is /CS mode 4-Wire withour busy indication (page 19 of Datasheet)

     

    The SDI line of ADC connected to IO pin of Controller…

  • RE: AD7982 SPI help

    Juan:

    Athought it's not Microchip, try having a look at the software in these projects, they might be able to help point things in the right direction.

  • Any better lower noise than ADC AD7982?

    In our application, we need to measure 10uV signal through ADC AD7982. But we found in this low signal area, measurement error is more than or near 10uV.  We check AD7982 Datasheet and see its typical noise is 40uV RMS. Too high for our application.

    My…

  • AD7982采集到的电压是实际电压的一半,频率是信号频率的两倍。

    使用AD7982进行数据采集,用ADA4940进行驱动,驱动芯片出来的信号正常,但是经过AD7982进行采集后,还原得到的信号电压幅值衰减一半,信号频率增大了一倍。AD7982的读取程序是采用的官方例程,应该无误。

  • Reflow temperature of AD7982

    Good day,

           Can you check the reflow temperature of AD7982, our prototype are all damaged under 220℃ .
