• AD7124-8 Internal temperature sensor conversion cause AINM_UV_ERR

    Hello :) 

    We're implementing an AD7124-8 as the main ADC in test equipment and I am in the process of writing up the firmware for controlling the module where the ADC is placed. I would like to measure the die temperature of the ADC to perform auto-calibration…

  • AD7124-8 write error

    AD7124-8 IC doesn't let me write the register values i want on the device. For example I can't start the device on full power mode or I can't change the AINM pins on the channels, it returns back to default AIN0 when i read back. 

    I can read…

  • AD7124-4/AD7124-8 FAQs

    Q1. The AD7124-4 and AD7124-8 have 3 power modes which one should I used?

    The end application will dictate the power mode to use.

    Common applications for the part are smart transmitters, process control input modules and low power or battery operated…

  • 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…

  • AD7124-8

    Hi I am using AD7124-8.i have set only channel0 .  RDY  bit  Bit 7  of  STATUS REGISTER  never goes low after first  time i read data register.  for first time it shows 0 status .but once i read  data register then sets and  never goes to zero .  can you explain…

  • Ltspice Model of AD7124-4 and AD7124-8

    Hey, Can anyone me to simulate AD7124 in Ltspice as i cannot find Spice model on the website. if someone has made it it would be great or else please help to create that IC in ltspice using IBIS model

  • AD7124-8, problem in CRC during continuous read mode

    Hello,

    I'm working with an AD7124-8 (more specifically with the EVAL-AD7124-8) trying to work with all of its functionalities.

    In particular, I'm working with the continuous read mode, with the checksum enabled.

    I encountered a problem, in fact…

  • AD7124-8, ENOB calculation

    Dear Technical Support Team,

    I want to measure ENOB for AD7124-8 ADC, by using EVAL-AD7124-8 evaluation board.

    I used a 16-bit precision sine wave as input. Via python (numpy.fft), I processed the conversion results and got the signal spectrum.

    ENOB…
