• ADAS3022 Power Supplies and Power-On Sequence

    What power supplies does the ADAS3022 require, and is there a power-on sequence
    that should be adhered to?

     

    The ADAS3022 requires these five supplies: AVDD = +5V, DVDD = + 5V, VDDH = +
    15V, VSSH = - 15V, and VIO = 1.8V to 5V. There is NO power…

  • ADAS3022 recommended ADC driver, external reference and reference buffer options

    What are the recommended ADC driver, external reference and reference buffer
    options?

     

    The ADAS3022 datasheet recommends the ADA4841 and AD8031 as ADC driver (to
    drive auxiliary input pair - AUX±) and reference buffer, respectively. Other …

  • ADAS3022 Accuracy Issue

    Hi,

    We are using EVAL-ADAS3022EDZ board to evaluate ADAS3022 chip.

    We intended to measure +/- 5V using this board & configuration value we have is 'F57E'.

    Below is the result. 

    VREF IN results +2.844 Voltage. 

    We are expecting linear output…

  • ADAS3022 code to voltage conversion

    Hi,

    I'm working with the ADAS3022 and would like to convert the 16 bit codes it produces into voltages. I am currently using the following formula:

    V = (CODE / GAIN) * (2*VREF)/32768

    This produces reasonable values, but it appears that the LSB value…

  • RE: ADAS3022 AVDD POWER

    RIO,

    There is no requirement for using a Low Drop Out Regulator as long as you understand the potential sources of error that can be introduced through the supplies. Please note that the switching frequency for the regulator you are proposing falls within…
