• About the spacing design with LED and Photo-diode for ADPD105

    Hi ADI expert,

    In order to prevent the "Excessive Interference", Could you help to provide about related design guide for LED and Photo-diode spacing design?

    Thank you

  • Is external pull-up with 3.3V possible when the GPIO0 of ADPD105  is set as open-drain.

    I would like to use as following.

  • 关于ADPD105 / 108在生产验证阶段,要如何验证芯片?

    专家您好!

    想请教一下ADPD105 / 108在生产验证阶段,要如何验证芯片有无问题?

    像是G-sensor都会订有容许的误差标准(例如:+/- 0.1G)之类的~~ ADPD105 / 108

    有这样的参考值吗?

    例如:设定LED电流:30 mA

    在什么样的条件下(覆盖或是暗室之类),必须得到怎样的ADC值?

    谢谢

  • ADPD105/107 gain and dark skin conditions

    While testing the ADPD107 on darker skin I have had trouble getting the response into a decent range for heart rate sensing even at max LED current, max gain, photodiode through single amp etc. Aside from increasing the optical efficiency and changing…

  • What happens if I don't calibrate the 32MHz clock on the ADPD105?

    We are currently doing measurements to compare the signal to noise ratios (SNR) of the PPG signals that we record with various setups. While doing so, we noticed that although our current software implementation does perform a calibration of the slow…

  • ADPD 105 Dual Slot ECG measure

    Hi there, 

    I am working with the ADPD105 and i try to measure a synchronous ppg and ecg signal with the dual slot settings. Its working perfectly if I measure just PPG signal but i could not find the right set up of the registers for the synchronous ecg…

  • Difference in PPG waveform observed in Eval board and traditional PPG waveform

    Traditional PPG waveform is as mentioned below.

    Image result for PPG waveform

    But the PPG wave  form output i am seeing in ADPD105 is as mentioned below.

    I am not understanding why i am observing this kind of output.

    Can you please explain me the Reason behind this?.

  • CN0409评估板问题

    你好,最近准备购买一套CN0409浊度测试方案的评估板,有如下几个疑问想确认下:

    1、CN0409需要一块ADPD105电路板和一个ADuCM360电路板,请问EVAL-CN0409-ARDZ这个是包含这两个板吗?还是EVAL-CN0409-ARDZ只包含ADPD105电路和比色瓶,对应的ADuCM360电路EVAL_ADICUP360需要另行购买?

    2、该方案中ADuCM360板EVAL_ADICUP360需要烧录对应的CN0409固件,如何购买到已经烧录好固件的ADuCM360板EVAL_ADICUP360…
