  • AD7686 SPI question regarding conversion

    I received this question from a customer:

    I’ve attached a picture of the logic analyzer capture. I have two questions.

    1. Am I preforming the acquisition/conversion correctly? I have from to read a bunch of analog values. The time to read each analogue…

  • What type of converters can the ADA4807 drive?

    What type of converters can the ADA4807 drive?


    The low broadband noise of 3.1nV/rHz and the low distortion of -139dBc makes
    the ADA4807 an ideal option for driving 16 and 18 bit SAR converters such as
    the AD7980, AD7685/AD7686 and the…
  • RE: AD7690 Readings / Output code

    Hi Alan,

    Thanks for the response.

    Is it not OK to use the AD7690 as single ended? Just taking IN- to GND like on the AD7686? We went for the AD7690 because of the 18-bits.

    In this case would the common mode voltage matter if I am only using IN+ ?

  • How do you set the conversion rate with the AD7686?

    The conversion rate appears to be from 0 to 500Ksps and the conversion clock appears to be internal, but I cant find a control reg to set the rate.  Oddly missing information in the DS...


  • RE: -URGENT- AD7688 analog input is instability.

    Hi Hiroyuki,

           The customer is having Vin+=DC voltage and Vin-= GND. What is the value of the DC voltage? This should work if Vin+= Vref. Please take note that the AD7688 is a differential ADC, it is expecting that the input of Vin+ and Vin- is opposite…

    Hi Jebas,

    PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…

  • AD7688: Using with ADuM1301

    We are planing to use either AD7688 or the AD7686 A2D-Converter due to their
    excellent SNR in our application. These converters are capable of a throughput
    of 500kSamp/sec, we want to use this full speed. Thus the aquisition time to
