    Hi ADI Engineers

    I try to make my post clear and no more than 256 words:

  • ADPD1080 MODE register


    I am trying to use an ADPD1080 sensor and for first tests and convenience I used the initializations from [1] for setting it up. When I am in the programming Mode (0x10 is set to 1), I can read back a 1 too. After setting it to 2 I don't read and…

  • ADPD1080 use with 3-pin LED/Photodiode combo


    We have an application where we wish to use the ADPD1080 with a three-pin optoelectronic device consisting of an LED and photodiode in the same hermetically-sealed package.  The cathode of the photodetector and the anode of the LED are connected…

  • ADPD1080 I2C SCL frequency

    Hi ADI Expert,

    on the circuit of my sensor there are I2C slaves on the same I2C-Bus: A sensor, which has a maximal serial data clock of 400KHz, and the ADPD1080. The datasheet of ADPD1080 shows only the typical serial data clock frequency. What about…

  • About ADPD1080 issue

    Hi ADI Expert,

    We've met a problem with using ADPD1080.

    We could communicate with the AFE by I2C interface and provide the power source of LED.

    However, the LED could not be turned on by AFE and, also, the MCU couldn't receive the interrupt of…

  • ADPD1080 32kHz internal clock oscillator

    Hi, ADI team,

    I have 2 questions for 32kHz internal clock oscillator of ADPD1080.

    1. Is it RC clock oscillator integrated inside ADPD1080?

    2. I'd like to know the oscillator deviation (might be called as the error)  includig ADPD1080 operating temperature…

  • ADPD1080 with high sampling frequency


    We're now working on a project to use ADPD1080 with 1KHz sampling frequency, which is supposed to be supported, by reading your manual.

    The evaluation board we're using is EVAL-ADPD2140Z. 

    However, neither using the provided software nor…
