ADS8694: ADS8694IDBT: Hi, I soldered this part to my PCB and I want to send some data to an STM32WB microcontroller

Part Number: ADS8694

I have some input signal, I want to collect this signal at a sampling frequency of somewhere in between 100kHz and 200kHz and using the 18 bits. After collecting this signal with the ADS8694, I want to send the data to the STM32WB MCU so I can store it and manipulate it. Also, my signal will be bipolar.

I am really new to this so I was wondering how I can set the sampling frequency in the ADC and how I can send the data to the MCU. I do not know if there are any tutorials or guides that I can follow to send the data correctly.

I would like to collect around 10 seconds of data or more, send it to the mcu and then store it in the mcu.

Besides sending the data to the STM32WB MCU, I also wanted to know how I can send it to an arduino.

Thanks for your time

  • Hi Gil F,

    The sampling rate is directly controlled by the /CS signal which is actually implemented as CONVST Start signal for activating a conversion. See the "ts" in the following timing.

    To retrieve the data from the ADC, you will have to following the timing below and make sure your processor can meet the timing requirements.

    The best material is the data sheet. Let me know if you have any further questions.

    Best regards,
