• RE: ADR421 VIN Range

    Hi  the specified voltage range for ADR421 is from 4.5V to 18V so the output will stay on the range of what is specified on the datasheet. 

    A Grade: 2.497 to 2.503

    B Grade: 2.499 to 2.501

    Best regards,


  • ADR421- Can the IC clamp current or sink current at its output.


    Can I use this IC as reference for a clamping circuit. Would it be able to sink or clamp any amount of current even if its a small percentage of



    Kindly advise me on the same.

    Hi everyone,

    I'm presently designing a new Board with the simultaneous sampling A/D converters AD7606-8. Thanks to Analog Devices, I have AD7606 schematic and PCB file, but I'm missing me some devices for my design project (working with Altium Designer…

  • ADR421 long term drift graph data

    I did not see the graph of long term voltage output drift in the datasheet for the ADR421.

    Is this something you can provide ?


  • ADR421 output voltage hysteresis specification

    My application has a temperature range of 0°C to 45°C. Is it possible for me to calculate (or approximate) the ADR421 output voltage hysteresis for this temperature range ?


  • ADR421ADR510_transistor count

    One of our customers need to know the transistor count for ADR510 and ADR421 in

    ADR421: 57 transistors

  • RE: AD7685

    See the first few pixels. I get a large swing of more than 100 counts. If the ADR421 Vref is too slow to respond and cap too far, I suspect few counts, not in the magnitude of 100. I don't have the cap right next to REF pin on the ADC. I put several…

  • AD7194: Voltage bias to thermocouple


    I working on Thermocouple amplifier based on AD7194.

    Could I use TC voltage biasing according picture below?


  • 4 AD7606 parallel to FPGA

    Hi, engineer!

    At present, the project needs to connect four ad7606s in parallel to FPGA through parallel port. Do you have relevant hardware design reference?

    The key issues are as follows:

    1.how to arrange the AD7606s properly?

    2. Multiple reference…
