THS3001: Is this part recommended for new designs ?

Part Number: THS3001
Other Parts Discussed in Thread: THS3491

Hi I saw Michael had posted in response to an earlier thread that this part wasn't recommended for new designs because of a resistor being too thin on the die. Yet when I look at the product page I still see this part and its variants as active - ditto for distributors. Can a TI person please let me know the official TI position, has the mask been re-spun to correct the die issue or corrected in some other way and is this part recommended bu TI for new products ? Just needing some clarity because it's the lowest power/noise high speed CFB amplifier in town. Thanks.

    And by town, you mean this particular planet?

    Hello Steve,

    I understand the existence of community threads and discussion about aspects of the THS3001 can appear to contrast the performance and product page for the device.

    I am looking into our own recommendations and communications on how to best address support of the THS3001.  

    I also align with Michael's comment; the THS3001 certainly has some universal appeal.

    Best,

    Alec

    Universal appeal? good one Alec, kind of like the sun's inexhorable gravitional pull - one must maintain enough orbital velocity (and hence distance) to resist plunging into its eternal fires. Another option Steve is perhaps a narrower supply current screen was implemented as the output stage bias variation show up in the supply current directly - long ago, very low output stage biases would occasionally break into maniacal oscillations in long running production systems.

    I would use the THS3491 if the current noise were similar or better but the THS3001 if it can be trusted to behave is the best show in town for our application. Also if the bias current issue still exists I'd e happy to restrict the supply to a higher voltage eg +/-15 or 16V. Alternavely though I don't like the smaller package for R&D I could switch to the HV version which has higher voltage and better thermal properties due to the metal PCB contact slug.
