• AD7714: Saturating the I/P channel

    When the AD7714 is sampling data if the input on the AIN1 line exceeds 3.5V
    with reference to AIN6 the input line and also the output of the AD8555 will
    stay fixed at this voltage ( in both buffered and unbuffered mode), even if the
    input to the…

  • AD7714: ALE pin as a master clock

    I am using an AD7714 with a 8051 micro.
    I am currently clocking it with 2MHz from a xtal oscillator, but I am
    wondering whether I could clock it with the 8051's ALE instead, which is
    also roughly 2MHz. However, the micro skips ALE pulses when…

  • I have a query regarding sampling an AD7714 ADC.

    I have a query regarding sampling an AD7714 ADC.

    I have three differential inputs and wish to sample these sequentially. My
    routines at the moment follow the flowchart on page 30 of the datasheet - but I
    perform 3 calibrations (each with different…

  • AD7714 vanish DRDY pulses

    AD7714 vanish DRDY pulses after chip init

    I try init my chip and if I do this there are no pulses on the DRDY pin.

    If I bypass init function I can read ADC values

    void main()

    {

       resetAD7714();

  • AD7714 Reading Incorrect Values

    Hi,

    I am using the AD7714 with STM32F411RE microcontroller and am having difficulty getting a reading that makes sense from a load cell.

    Here is my code for the initialization: 
    void loadcell_init()
    {
    uint8_t init1 = 0x24;//0b00100100
    uint8_t init2 = 0x61;…

  • AD7714 REF IN(+) Current

    Hi,

    I'll design a 2.5V power supply for the reference of AD7714.  My spec is REF IN(+): 2.5V, REF IN(-): 0V and Ta=-5 degC~+50 degC.

    Could you tell me a current rating of the REF IN(+)?   1mA is enough?

    Regards,

    Kazu
