• ad7671不工作

    按照参考电路进行设计,单端输入,悬空采集都正常,当使用电源作为输入源时,一开电源开关,adc就不正常了,数字口cvert和busy都正常,但是数据线一直是0,请专家指教。

    Hi Tyler,

    Thanks for the response.

    Could you pls tell me how to make this "synchronous to the SPI read instructions which read back the ADC results". Could you pls share the sample code if any. also pls share the Blackfin DSP code which you have…

  • AD7671 interfacing with ADSP21369 using SPI protocol for SERIAL mode

    Hi All,

    I am using ADSP21369 and AD7671(ADC) in my project. ADSP21369 is configured as master and AD7671 as slave in SERIAL mode.

    AD7671 is set in WRAP mode. I am giving input to IND(4R) and INA(R) as 2.5Volts.

    SPI protocol is used to interface b/w the…

  • Problem in reading MISO from AD7671 which is interfaced with ADSP21369 using SPI

    Hi,

    I am using AD7671 in my project which is interfaced with ADSP21369 using SPI. I am using 12MHz clock. ADSP is the master.

    INA(R)=2.5V

    IND(4R)=5V

    INB(2R)=INC(4R)=0

    MISO output is changing for every clock cycle. I am not understanding the problem.…

  • AD7671 Output has step

    Hi,

     When I use AD7671 to convert signal (1Hz to 1kHz), I found steps in the output.

    Attachment figure 1 is the waveform, where green line is input of AD7671;yellow line is the output of AD7671 (a DCA output, the DAC operated well).
