• AD7768 AND ADA4922-1

    Hi All,

     I am working one of my project called 8 Channel Receiver.

    In this project, I have 8 Channel of differential Analog input.

    I will get the all the 8 Channel input from external source with the range of 10Vpp as Max .

    I have mentioned my design block…

  • EXTCLK application for AD7768-1

    Due to some special demands, we need to use External XTAL.

    But we can not find the input voltage of EXTCLK. Could you help to check this issue on AD7768?

    Now our XTAL is 10MHz@0.8V, sinewave, low jitter and drift. We can not make sure it can work on…

  • ADI's New 24 bit, Single Channel, Sigma Delta ADC with Power Scaling - The AD7768-1

    The AD7768-1New is a low power, high performance, Σ-Δ analog to-digital converter (ADC), with a Σ-Δ modulator and digital filter for precision conversion of both ac and dc signals. The AD7768-1 provides a single configurable and reusable data acquisition…


    Hi Kapiliitd,

    Depending on the level of anti-aliasing filtering required it may sometimes be necessary to have a higher order filter in order to have a sharper roll off. In this case, a 3rd or 4th order filter should be sufficient. Page 57 of the AD7768…

  • RE: AFE for AD7768-4


    The recommended drivers for AD7768 are ADA4945-1, ADA4896-2, ADA4940-1 for Fast Power Mode; ADA4945-1, LTC6363, ADA4805-2 for Low Power Mode; and ADA4945-1, ADA4807-2, ADA4940-1 for Median Power Mode. The AD7768 can operate up to 5V analog supply so…

  • Interfacing the AD7768/AD7768-4 to a microcontroller

    The AD7768/AD7768-4 outputs data as a master, meaning that the device continuously streams data and it is the user's task to read the data as it is output. Therefore the microcontroller that interfaces to the data output lines must be configured as…

  • AD7768-1 exit from continuous read mode

    In the datasheet EXITING CONTINUOUS READ MODE, I found the following description.

    "when CS is permanently tied low, write 0x006C to exit continuous read mode when using the 3-wire version of the interface."

    would you teach me what exactly I…

  • RE: AD7768芯片是否可以应用在地震检测仪器数据采集中?它 的灵敏度是否能够和ADS1282相媲美?

    AD7768输入范围比ADS1282大, 吞吐率高,但没有集成PGA.


  • AD7768 FAQ - What front end driver amplifier is suitable to drive the AD7768?

    There are many amplifiers suitable to drive the AD7768/AD7768-4. Choosing the most suitable amp can be a difficult task, especially when there are constraints on the system power. In order to achieve the lowest power and highest accuracy in a data acquisition…
