• 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 input protection

    Hi

    I'm using AD7124-4 in my design. Input to this device is the output of an instrumentation amplifier whose supply is 31V and -5V. By any means if my instrumentation amplifier goes to saturation there is a possibility that ADC can get negative input…

  • Development board for AD7124-4

    Hi,

    I was wondering if there was a development board for the AD7124-4. The evaluation kit EVAL-AD7124-4SDZ, but I can't seem to access the MISO, MOSI, SCK, CS lines (or am I missing something?). I'm primarily looking for writing a driver for my AD7124…

  • AD7124-4 PGA Input-Voltage Requirements

    Hi,

    I'm working on an RTD measurement design and comparing the specifications of AD7124-4 from ADI and ADS124S06 from TI.

    In ADS124S06's datasheet, there are equations for PGA input/output range (refer to the following figure). According to these…

  • AD7124-4 CRC

    Hi

    I have a question regarding AD7124-4 CRC Checksum.

    I can easily turn on the CRC check for ROM and RAM but I can not understand CRC for SPI communication.

    I turn on CRC SPI by enabling the SPI_CRC_ ERR_EN bit. Thereafter I expect that receive the CRC…
