• AD7767 SNR vs ODR

    Hi All,

     

    Sigma-Delta ADC such as AD7794 has data of SNR vs ODR (Output Data Rate) performance in its data sheet.

    Can I see the same SNR (or ENOB) vs ODR data of the AD7767 ADC?

     

    Best Regards,

    Ricky

  • EVAL-AD7767-2EDZ - continuous data logging

    Hello!

    I've bought EVAL-AD7767-2EDZ and CED1Z. Now I need to save data from ADC in continuous mode to file. Is it possible?

    For example, when I use EVAL-AD7195EBZ I can save data to file as long as I want.

    Thanks!

  • AD7767 Digital Filter - plot vs data

    Hi,

    We have used the AD7767 for many, many applications over the last few years very successfully.  For the latest project, some questions have arisen about the transition region of the digital filter from pass band to stop band.

    The data sheet (Rev…

  • Settling Time of AD7767?

    Hi,

    I am confused by information in data sheet.

    On page 4 (footer) it is written: "Digital Fliter Response - Settling time (latency): 74/ODR µs".

    What latency for 32kHz output rate?

    74/32= 2.3 µs or 2.3 ms?

    How about the step-response…

  • MCLK supply for AD7767-1

    Dear Support team,

    I would like to AD conversion processing in synchronization with the external pulse.
    Is there a problem in the following procedure specifically?

    1. MCLK port holds Low state until receive synchronization pulse from external.
    2. When…

  • AD7767-2 About to pin connections

    Hi,

    My question would be a very simple question. I'm asking because I can't perceive it because I'm a student.

    I intend to connect Raspberry pi with AD7767. However, I can't be sure which data pins of the AD7767 are MOSI, MISO, SCLK and CS…

  • RE: AD7767 2's complement output not as described in Data sheet

    Thanks your reply was helpful in finding the problem. It turns out the problem with the setup of the SPI port

    hspi1.Init.CLKPolarity = SPI_POLARITY_LOW;     // caused the readout to miss the MSB 

    The change below resolved it

    hspi1.Init.CLKPolarity = SPI_…

  • RE: is AD7767 SCLK need

    Hi,

    The number of SCLK falling edges that occur when DRDY is low must match the number of devices in the chain multiplied by 24 as shown in the figure. You can either provide continuous SCLK or start providing the SCLK after DRDY and CS low as long as…

    Hi,

    The customer is asking on AD7767, serial timing diagram at Figure 3. and Figure 4., that they indicate SCLK of 23(Figure 3.) and 24(Figure 4.) pulses for reading 24 bits of data. Here, if we put 24 or more pulses in case of Figure 3., or 25 or more…
