• 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 a…

  • AD7768/AD7768-4 FAQ - Clock Selection

    The AD7768/AD7768-4 MCLK can be applied by using one of the three different options that are available to the user. The purpose of this document is to further explain these three options and how they are configured. The three options are: external CMOS…

  • If I enable the analog input buffers on the AD7768 (or AD7768-4, AD7768-1New, AD7761) do I still need an external ADC driver opamp?

    If I enable the analog input buffers on the AD7768 (or AD7768-4, AD7768-1New, AD7761) do I still need an external ADC driver opamp?

    The precharge buffers are not full buffers and do not replace the external driver opamp(s). Some further details on how…

  • Timing issue for AD7768-4

    Dear Sir:

                  We follow datasheet  figure 2 and 3  to measure data interface timing for AD7768-4. However , There are some specification out of range datasheet as below test result and waveform , Does ADI has some suggestion to us?

  • AD7768-4使用外部有源晶振时XTAL1怎么接

    大家好,请问AD7768-4使用外部有源晶振时XTAL1怎么接,目前该引脚是浮空状态,我使用的是引脚控制模式,DCLK和DRDY都有输出,但是DOUT0-3芯片错误位为1,3通道4通道滤波器饱和,通道ID是对的,reset引脚通过1k的电阻上拉到IOVDD

  • AD7768-4

    Hi all,

    I have doubt after writing to the SPI register set do I need to use start or synch_in signal to reflect changes in register set, if not using start signal should be tied to pull up as per datasheet, then what is the status of sync_in signal should…

  • [AD7768-4] IOVDD-Ciruitry & SPI-Voltages

    Dear all,

    I have a question regarding the IOVDD-ciruitry which is for me not clear from the data sheet.
    What I understood is that there are two ways of using IOVDD:
                a)by supplying a voltage like 3,3V which leads to the usage of the internal LDO which…
