  • Vref in ADV7125

    Hi.

    If I use the AD1580 for reference voltage (Figure 10, pin 36 datasheet), what is the value of Vref in the formula?

    IOR, IOB (mA) = 7989.6 × Vref / Rset

    Vref is 1.235 V (internal reference voltage) or 1,225 V (provided by the AD1580)?

  • RE: ADP151 for Dual Power Supply

    You cannot use a positive linear regulator in a negative supply.

    The linear regulator would regulate with respect to the -5V and not with respect to GND.

    you could use a shunt regulator or a zener instead. Like AD1580 for example

  • RE: Supply voltage for ADV7125 and decoupling of VREF pin

    Hi

    This might be repeated question.

    What is ADI recommended chircuit about ADV7123/7125 VREF pin when internal reference used?

    0.1uF decoulping to VAA was mentioned in the schematic of old datasheet and P18/24 of the latest datasheet

    but 1uF decoulping…

  • RE: ADV712x DAC References

    The recommended approach when using either the ADV7123 or ADV7125 is to use an external reference (as per datasheet) e.g. AD1580.

    Attached is a reference schematic - also covered in the datasheet.

  • RE: AD7714 REF IN(+) Current

    Hi,

    Yes, I think the current is around some uA level only. This thread may be able to help you regarding the actual measurement. https://ez.analog.com/message/114854?commentID=114854#comment-114854 

    We also have some recommended voltage reference parts…

  • RE: Please help me to review the schematics of ADV7123

    Hi,

     The schematic would be covered in datasheet,Please crosscheck. Refer section - Circuit description and operation in datasheet.

     Refer here Design and Layout of a Video Graphics System for Reduced EMI (Rev. AN-333)  at https://www.analog.com/en/products…

  • ADV7125 Vref Value

    Hi everyone,

    I use the schematics in Datasheet (Figure 10. Typical Connection Diagram) on my design except AD1580 zener.

    I want to use adv7125 for composite video, so IOR and IOB terminated with 50ohm which is same impedance value with IOG. IOG is doubly…

  • RE: ADV7343 noise

    Turning off PLL 1 fixed the problem.  Is it a good idea to turn this off?

    I'm only using DACs 1 to 3 so its hard to tell if its happening on DACs 4 to 6.  It's definitely happening on DACs 1 and 2.  DAC 3 is chroma and I haven't noticed it there…
