• RE: AD4114 calibration

    Hi, 

    There's a limitation in the calibration range of the ADC gain for a system full-scale calibration on a voltage input is from 3.75 × VREF to 10.5V x VREF. However,  if 10.5 × VREF is greater than the absolute input voltage specification for…

  • AD4114 Continuous Conversion Mode and Continuous Read Mode

    Hello,

    In the process of using AD4114 encountered problems, please help to answer.Thank you very much!

    1. When setting AD4114 to Continuous Conversion Mode and Continuous Read Mode, the number of consecutive Read channels is random, and some channels…

  • AD4114使用过程遇到问题

    Hello,

      在使用AD4114的过程中遇到问题,请帮忙解答。多谢!

    1.设置AD4114为Continuous Conversion Mode和Continuous Read Mode时,连续读回来通道数是随机的,并且某些通道还读不到,怎么解决?

    设置流程为:
    a、分别使能16通道,例如使能通道0通过SPI设置发0x10801000,使能通道1发0x11803000等等
    b、设置Continuous Conversion Mode,设置01寄存器,通过SPI发0x01200c00
    c、设置Continuous…

  • Q1. What is the difference between the AD4111/AD4112/AD4114/AD4115?

    Q1. What is the difference between the AD4111/AD4112/AD4114/AD4115?

    AD4111 and AD4112 are pin compatible and have an almost identical feature set except the AD4111 has a unique solution for open wire detection from a single 3.3V/5V supply. Details can…

  • ADUM5411 I/O Voltage on EVAL-AD4114 is not at V(DD1)

    Hello, I have an EVAL-AD4114 I'm evaluating. It has an ADUM5411 incorporated into the board. I am not using an SDB, I'm interfacing via the arduino headers though I am not using an arduino. The board is being powered from a bench supply via J4 with 5V…

  • Q14. What is the recommended initialization and register configuration sequence for AD4111/AD4112/AD4114/AD4115?

    Q14. What is the recommended initialization and register configuration sequence for AD4111/AD4112/AD4114/AD4115?

    On power-up, it is advisable to perform a reset by writing 64 consecutive ones to the part.

    This will reset the serial interface, and it will…

  • Q3. What is the recommended anti-aliasing filter required for the AD4111/AD4112/AD4114/AD4115?

    Q3. What is the recommended anti-aliasing filter required for the AD4111/AD4112/AD4114/AD4115?

    For the AD4111/ AD4112/AD4114/AD4115 the recommend anti-aliasing is 4.7nF/180Ω as this combination will give you the optimum performance and were used in t…

  • Q8. Why are the Analog input buffers required for voltage measurements AD4111/AD4112/AD4114/AD4115?

    Q8. Why are the Analog input buffers required for voltage measurements AD4111/AD4112/AD4114/AD4115?

    The Analog input buffers should be enabled for voltage Analog inputs as these provide a low source impedance to the sampling ADC. If these buffers were…

  • Q9. What’s the equivalent input impedance for a pair of voltage input pins of AD4111/AD4112/AD4114/AD4115?

    Q9. What’s the equivalent input impedance for a pair of voltage input pins of AD4111/AD4112/AD4114/AD4115?

    Below is the detailed figure of the voltage input stage. Please take note that the 10MΩ is not relevant to the VIN 1/10X transfer function…

  • Q15. How many data registers does the AD4111/AD4112/AD4114/AD4115 have to store conversion results for each channel?

    Q15. How many data registers does the AD4111/AD4112/AD4114/AD4115 have to store conversion results for each channel?

    The AD411x devices have one data register, therefore only one conversion result is stored at any given time.  When several channels are…
