• RE: AD4115

    Hi, 

    AD4115 could be use as it is within the required range, but this part is more recommended for higher input voltage ranges, usually +/-10V. You may consider using the AD719x family as it is more suitable for load cell application due to its lowest…

  • RE: AD4115 AVDD range.

    Hi Angelo, 

    Apologies. It’s a typo error. Please follow the specs table the supply is 4.5V to 5.5V.

    Thanks for the feedback. We will correct this in our future datasheet update. 

    Thanks,

  • 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…

  • External Crystal on AD4115 and EVAL-AD4115SDZ

    I just purchased an EVAL-AD4115SDZ so I could evaluate the AD4115. I've noticed that it works as expected after a reset using the internal clock - writing 0x0000 to the ADCMODE register and dropping CS indicates continuous conversions at 125Khz on the…

  • 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…

  • 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…

  • 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…

  • Appended Status Byte Corrupted on AD4115 with 125Khz Data Rate

    • I have an EVAL-AD4115SDZ connected to my uP with a set of short jumper wires.
    • My SPI clock is 8Mhz.
    • I have a single channel enabled (CHAN0) and it is performing a single ended measurement.
    • I'm using the SINC5 filter and have configured the registers for…
  • 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…

  • RE: Still having Issues with Multiple Channels on the AD4115 in Continuous Read Mode

    Thanks Wally. I will also closed the other item about AD4112 which I believed having the same solution.
