ADS1293: Calibration required in product life

Part Number: ADS1293

Hello All, this question as been alredy posterd but I wish to know if calibration is actually required or not during product life. Evidence supports that they work just fine without recalibration. If that is the case, could you please share some technical documentation/reports regarding this matter?

.If needed, please contact me privately

  • Hi,

    The Chip/IC itself doesn't need any calibration. TI doesn't have any technical document to show the device(IC) itself requires calibration nor has any document or comments regarding the calibration for the Chip/IC

    However, whether the final/end products that customers are developing require product level calibration or not depend on the designers&engineers as it depends on many other factors such as -
    environment noises, EMI, electrodes, cables, gels, skin conditions, body, breathing, air in lung, walking/talking, skin conditions, environmental surroundings, etc.
    as well as designers/engineers and products' designs(e.g. cases, chassis, battery or line powered, etc), operating/usage environments, etc.

    So, it will require designers/engineers to test, collect data, study, analyze, verify and validate, and tune, reiterate/revise under different settings mentioned above before making final decisions for Product level calibration.

    E.g. it really depends on whether the designers/engineers and the end user use the end/final products in a very dry or wet or hot or cold environment or different electrodes or different electrode cables and/or cable length or noisy environment, etc. Thus, products designers/engineers need to study and make decision whether to do products level calibration or come up any algorithm to adapt those situations.
