• 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…

  • 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…

  • ad7768-4

    Hi there,

    I have one ad7768-4 evm and trying to disable the precharge buffer. I have two differential input right now and I cannot turn off all of the precharge buffer. May I know how I can make the setup?


  • Evaluation Board AD7768-4

    I have to do mechanical experiment and capture 4 analogue signals.

    I plan to buy evaluation board AD7768-4 and use external processor via SPI as well as directly connect to PC.

    I need to understand if I may do what I want using evaluation board AD7768…

  • AD7768-4: Initialing secquence in Pin MODE

    Dear all, 

    I am designing a circuit that drives only one AD7786-4 in Pin Mode.

    It is connected to a microcontroller and the connected microcontroller can get data in SPI Slave mode.

    We think that the filter setting and FORMATx setting for Pin mode operation…

  • EVAL-AD7768-4 Software Issue

    I'm using the software application for the EVAL-AD7768-4 evaluation board. Whenever I attempt to change settings on the 'Configuration' tab in the software I get a condensed pop-up window (except when selecting the 'Precharge Buffers' option) that won…

  • Measuring AC Voltages Directly with the AD7768-4


    I am looking to directly measure a [-2.5,2.5] VAC Signal with the AD7768-4 Analog to Digital Converter. My original plan was to have Vdd=2.5V, Vss=-2.5V, but I'm wondering how to wire the +/- Reference Voltage Inputs. Can I simply use the ADR4525WBRZ…

  • How can I input bipolar signal to EVAL-AD7768-4?

    Hi all, 

      I want to sample single ended-bipolar signal(about 1.8Vpp, +/-0.9V) with AD7768-4 Evaluation Board. But, as datasheet said, the Absolute Analog Input Voltage Limits is AVSS to AVDD(0V to 5V) when AVSS=0V. 

     I want to know if I can change the circuit…

  • AD7768-4 issue.

    Dear Sir:

                    We tried to design AD7768-4 for our sensor circuit , But I have a issue from ADC input pin. When turn on AD7768-4    and AINx+ and AINx- are floating , we can measure 5.28V DC on those pin. when we remove VDDIO1.8V then 5.28V vanish. What's Wrong…
