Design PPG sensor using AFE4403 and DCM04(AMPKorea)

Other Parts Discussed in Thread: AFE4403

I'm going to design PPG sensor using AFE4403 and DCM04(AMPKorea) for whist device.

I wondering about 'TI Designs' (http://www.ti.com/product/AFE4403/toolssoftware

Miniaturized Optical Heart Rate Reference Design(SFH7050)

=> Is it possible using DCM04 and AFE4403 for PPG(Measure Heart Rate)?

 

Please, Answer ASAP.

 

  • Hello Inho,

    I couldn't find the DCM04 datasheet anywhere online. Could you attach the DCM04 datasheet?

    There is a TI design based on AFE4403 and DCM03 that you may want to look at for your reference.

    Miniaturized Pulse Oximeter Reference Design

  • Thank you for your reply. I attached DCM04 datasheet.4377.DCM04(PPG센서).pdf


    And, I answer again because I questioned not rightly on yesterday.

    "Miniaturized Pulse Oximeter Reference Design(DCM03)" and "Miniaturized Optical Heart Rate Reference Design(SFH7050)"

    which is a best design for whist heartrate sensor; DCM03 or SFH7050?

    That page is recommended LEDs. But TI Design documents is Osram and NJR, OSI. 

    I confused about which LED is very properly.

    Let me way to best good solution or guidance.   


    Best regards

  • Hello Jeon,

    Thank you for pointing out that the optical sensor recommendations in the FAQ section was missing the two sensors: SFH7050 from OSRAM and NJL5310R from NJRC.
    I have updated the list.

    All the recommendations in that list are good candidates for heart rate monitoring.
    The selection of the optical sensor depends on the application, size and cost of the sensor, measurement site and a whole lot of other parameters like spectral response, sensitivity, response time, and optimum separation between the LED and photodiode. Refer to the article (www.mdtmag.com/.../designing-heart-rate-monitor-wearable-devices) that discusses about how to design an OHRM solution in a wearable device under the most challenging conditions.

    You may want to test the sensor in your application before making a decision.
    Since we have not tested the DCM04 sensor with AFE44xx, we will not be able to add DCM04 to the recommendation list.
    But since DCM04 is similar to DCM03 except that the RED LED is replaced with Green LED, you should be able to test the sensor with AFE4403.
