• RE: AD4112 REG_CHECK

    Thanks for your answer,Jellenie

    Could you tell more about "internal fuse values or registers" which could  make different  chip gives different results,  I just want to use regcheck to check whether  my every AD4112 have the same configuration,…

  • Q1. What is the difference of AD4116 to AD4111/AD4112/AD4114/AD4115?

    AD4116 is the only is the only member of the family with a 10 MΩ input impedance and with additional low input voltage specifically design to have better performance at lower input ranges useful for current measurements which allowed extra rooms for any…

  • Can the AD4111 be a drop in replacement for the AD4112?

    Due to the global chip shortage, I'm having a difficult time sourcing the AD4112. However, after reviewing the AD4111 datasheet, it appears that I can use it as a drop in replacement. I do not plan on using the open-wire detection features of the AD4111…

  • AD4112 input-voltage range

    In Datasheet of AD4112, 1st Page says "±10 V inputs", Page 27 Says (under VOLTAGE INPUTS)"enable an input range of ±20 V from a single 5 V power supply". Will Uni-polar setting give range of 0 to +40V & Bipolar will give +/- 20V?…

  • 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…

  • 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…

  • Q5. Why are the onboard Analog input buffers not required for current measurements AD4111/AD4112?

    Q5. Why are the onboard Analog input buffers not required for current measurements AD4111/AD4112?

    To enable currents to be measured below 0mA, the Analog input buffers should be disabled for current measurement. This would extend the ADC input range to…

  • 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…

  • 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…

  • Unexpected Behavior with Continuous Read Mode on AD4112

    I'm trying to perform a continuous read of four channels on the AD4112 as described on page 35 of the datasheet. I have channels 0, 1, 2, and 3 configured and enabled with different combinations of single ended and differential voltage mux inputs along…
