    Hi  M. Hufnagel,

  • Hi There, I'd like to use this chip as a differential amplifier with asymmetric power suply of VCC=160V and VEE=-5V. Can this chip be used in this way ?

    Hi AlexBalyabo, you are correct - that scale should say kHz.  Thanks for catching the error. I am putting in a request to correct that for the next rev of the datasheet.  Good eye Slight smile

  • Fig.59 in the datasheet shows the dynamic SOA. The frequency is given in Hz. Is this a typo? I assume, it has to be in kHz.

    Please, clarify.

    Thank you for your interest! The product is released to production but currently out of stock due to high demand.  We are expediting to resolve this as quickly as possible.  Best Regards, Brian Beucler

  • Hi, we are very excited to use this opamp in one of our new circuit boards. When the product will reach the market.

    Hi Jiri.Kol, thanks for your question.  IEC 60664-1 specifies minimum clearance and creepage distance for PCBs and conductors on a package to be 1.25mm at 250V.  The ADHV4702-1's pins spacing meets this requirement.  Best Rgds, Brian Beucler

  • Dear,

    for ADHV4702-1, I expect that I will not be the only one who will ask how engineers in ADI estimated clearances (and creepages) on device package and associated footprint on PCB. For 220V-rated device, I do not see a chance to meet requirements for safety standards for PCB design. In case you have proven way how to make such design compliant i.e. with UL-61010, publish it please.
