• FAQ. How to ensure synchronization of conversion between multiple AD7124-4/AD7124-8 devices?

    Answer: To ensure synchronization between multiple AD7124-4/AD7124-8 devices, the same master clock must be used for all devices. If the AD7124 internal clock has been used, then one ADC serves as the master and uses its own internal clock and this clock…

  • AD7124-4 FS Setting in Virtual Eval Tool


    When I try to set FS = 1 in Virtual Eval Tool for AD7124-4 I get following error: "Fs of 1 is outside range for the AD7124. The Fs for the conditions selected must be between: 4 and 2047. Please enter a valid Fs." But AD7124-4 datasheet says…

  • AD7124-4 DOUT/RDY Pin Toggling


    a similar problem came up in this forum, however i couldn't find a working solution for me.

    The Problem is the SPI communication with the AD7124-4 at 3.3V.

    I use the following setup:

    AVDD = IOVDD = 3.3 V


    When i run the…

  • FAQ: What is the equation for calculating Internal Temperature Sensor for AD7124-4/AD7124-8 in unipolar mode?

    FAQ: What is the equation for calculating Internal Temperature Sensor for AD7124-4/AD7124-8 in unipolar mode?

    For AD7124-4/AD7124-8 the sensitivity of the internal temperature sensor is 13,584 codes/°C, approximately when Vref = 2.5V. Both unipolar and…

  • AD7124-4 AD7124-8 ESD on current output pins


    Is there a recommended ESD protection circuit for the current output pins on the AD7124-8?  I am using AIN0 and AIN1 to source 500uA of current to measure a 3 wire RTD.  Since these pins are directly wired off the chip and out of the board they will…

  • AD7124-4单端输入问题


  • FAQ. When I need multiple analog input channels, should I use multiple AD7124-4/AD7124 or an external MUX?

    Answer: For a system that requires multiple channels, one AD7124-8 can support up to 8 differential/15 single ended input channels and one AD7124-4 can support up to 4 differential/7 single ended input channels. If the system requires a greater number…
