• ADT7320, ADT7420 - Requirements to setup the ADT7320/ADT7420

    What additional components do I require to setup the ADT7320/ADT7420?


    Both parts require a 0.1uf ceramic and 10uf tantalum decoupling capacitors. The
    interrupt and critical limit pins will also require 10kΩ pull-up resistors. The
  • ADT7320, ADT7420

    Does the ADT7X20 need to be calibrated?


    No user calibration is required with these sensors because ADI pre-calibrates
    all devices using our high accuracy test solution.
    Because each device leaving the factory is fully calibrated, all…
  • ADT7320 setup


    I have an ADT7320 eval board connected to a microcontroller that has SPI set up for 16.66 MHz SCLK and 24-bit data words.

    I sent 32 1's to reset and consistently get 0xE180 when I read the ID.

    If I shift left to get rid of most significant bit…

  • ADT7320 16-bit results


    I'm using ADT7320, but can't get 16-bit results of measurement.

    After power on, I boot 32 consecutive 1s. Then I load to the configuration register value 0x80. After 260ms I read the result, but in all cases I only get a 13-bit result.…

  • ADT7320 operating principle


    One of the customer wants to know ADT7320 operating principle.

    I found the block diagram show only "temperature sensor".

    Is it possible to show us the principle?


  • ADT7320 RDY bit

    I recently used the adt7320 digital thermometer but currently i'm
    experiencing a strange behaviour of this product.

    I set the operating mode to continuous conversion by setting bit 6 and bit 5
    of the configuration register (0x01) to zero.


  • ADT7320, ADT7420 - Communication with ADT7x20

    How do I communicate with the ADT7320 and ADT7420?


    The ADT7320 has a SPI 4-wire interface and the ADT7420 has an I²C 2-wire
    The sensors will typically complete a conversion every 240ms and update the
    temperature register…
  • Question about ADT7320

    English data sheet

    but Chinese data sheet

    I don't know if TA = -10°C to +85°C,VDD = 3.3V.

    Accuracy ±0.20°C or ±0.25°C?


  • ADT7310/ADT7320 SPI bus transactions

    To read or write data to and from the ADT7310/ADT7320 registers, the length of the transactions on the SPI bus can be 16 or 24 bits. My microcontroller only supports SPI bus transactions of 8 bits each. Can split the 16/24 bus transactions required by…

  • ADT7310/ADT7320 lifetime vs temperature

    Dear Analog Devices engineers,

    In my project, I need to monitor temperature variations of some devices. The temperature of one of them is set at 120°C. The temperature is supposed to be quite stable (except during power on and power off of the system…
