• Current rating for AD7124-8 - external power supply

    Hello,

    I can't find a current rating for the AD7124-8 evaluation boards, only that the input voltage range is 7-9V. (It looks like the external power source is sent through a linear regulator (ADP1720), but I also couldn't find an input current for this…

  • 8 RDTtemperature sensors connection to AD7124-8. possible?

    Hello experts:

    I am looking for a way to connect 8 RDT temperature sensors to AD7124-8.

    I am doing it today with an external analog multiplexer and RTD reader module.

    I would like to change the design to one main chip only and AD7124-8 seems to be able…

  • AD7124-4/AD7124-8: FAQs

    Question:

    What is the data output coding format used in AD7124-4/AD7124-8?

    Answer:

    On the AD124-4 & AD7124-8 sigma delta ADCs, two different coding options exist unipolar and bipolar coding. Unipolar coding is used to represent positive voltages only…

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


    Hi,

    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…
