ADS1292: demo kit for signal processing

Part Number: ADS1292

Hello everyone,

A customer is evaluating ADS1292 demo kit, but there are three problems to be figured out, could you please help? thank you!

  1. Is it that channel 1 can only be used to measure respiration? If not, can respiration and ECG signals be measured in different time by changing the internal registers?
  2. Should the acquired data of  respiration and heart rate be processed by algorithm filter? If so, how to get the filtering algorithm?
  3. Is it possible to process the acquired data of  respiration and heart rate by MSP430?

Best Regards,

Hao

  • Hello Hao,

    Thanks for supporting our ADS1292!

    1. Channel 1 can be used to measure either respiration or ECG if they are using the 'R' version of the ADS1292 (ADS1292R). As you mentioned, you simply need to adjust the register settings to disable the internal respiration modulation/demodulation circuitry. The ADS1292RECGFE may have already configured the signal chain components for respiration measurements. If you want to measure ECG, you will need to follow the instructions at the bottom of the schematic page in the User Guide to modify the components for ECG. However, I recommend leaving the components as-is and evaluating ECG performance on Channel 2. You can expect the performance to be the same.
    2. Filter algorithms are specific to each customer's end application. For similar products, the algorithms that one customer uses may differentiate them from competitors. Your customer will have to research and design their own filtering algorithms.
    3. This is a very broad question - the answer depends on what else the MSP430 is controlling and what type of filtering the customer wishes to implement. I do see a lot of low-power ECG applications using microcontrollers such as MSP430, so it's likely possible, but that is really beyond the scope of our forum.

    Please let me know if you have any additional questions.
