• RE: ADPD103 Drives a LED ( 5V~7V@20mA )

    For some reason I assumed that we were talking about the ADPD105 since it's the latest device in the family. If this is a new design, then you should be looking at the ADPD105 (or ADPD107 if you wanted SPI). The ADPD105 is backwards compatible. There…

  • 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…

  • Regarding Output Voltage Value

    For the Above circuit the Output of AD8232 is 0.9V offset +( Diff o/p * system gain ). This output is fed to the ADPD107 PD input configured in TIA ADC mode.

    for the out put of TIA ADC should we Consider  eq 11 of Page40?

    By using ADCout we should…

  • RE: ADPD105 TIA ADC mode configuration

    Hi Ganesh,

    The maximum sampling rate of our evaluation tool is going to be limited by the communications interface over the UART. In practice, the fastest I've ever been able to get the Wavetool to run is ~1000Hz for single channel operation, 16b data…

  • ADPD4001  | ADPD1081 | ADPD188GG | Best Configuration for PPG (2 Green vs 3 Green, Red LED, and IR LED)

    We are working on a real-time wearable PPG solution. We understand that either ADPD4001 or ADPD1081 can be used.

    Q1) I am wondering if you could comment on the accuracy and power consumption of those two ICs. Which one is recommended by you for a wearable…

  • Multiple questions about ADPD105 and ADPD108 and their evalboards

    I work for a Medical device R&D company. We are currently working on a project where we are trying to detect physiological signals deep under the skin using IR which requires an emitter to detector distance of 4+ cm. Because of this, we need to use a…

  • 物联网领域常用的6大传感器

    在IoT时代,传感器无疑是其中最关键的组件之一。今天版主就说说那些在物联网领域常见的六种传感器。当然,除了这六种,还有一些常见的传感器,欢迎坛子里的大侠进行补充,与大家一起讨论。

    距离传感器

    距离传感器,又叫做位移传感器,是传感器的一种,用于感应其与某物体间的距离以完成预设的某种功能,被广泛应用于手机和各种智能灯具中,产品可以根据用户在使用过程中的不同距离产生不同的变化。

    光传感器

    光传感器就是利用光电效应,通过光敏材料将环境光线的强弱转换为电量信号。光传感器主要应用在电子产品的环境光强监测上…
