OPA330: Dimensions + extra Quiescent current

Sven Jansen
Prodigy 220 points
Part Number: OPA330
Other Parts Discussed in Thread: OPA2333, OPA333, OPA2330

Hello,

I,m looking into OPA330 for a project. Package dimensions are very important for this.
In the datasheet of OPA330, I only see maximum values, but we are also interested in typical values, is it possible to provide these? (especially thickness

And another question about this part;
We first wanted to use OPA2333 in KGD version as its quiescent is less. I'm wondering what the differences are between OPA2333 and OPA330 what makes this current increase that much (as they seem to be identical parts except for this).

Thanks,

Sven

    Sven,

    In addition to showing maximum package dimensions, there are also typical values shown in the drawings. Thus, for example, the typical thickness of SOT-23-5 package is 1.1mm+0.15mm – see below.

     

    As far as your second question goes, first of all, OPA2333 is a dual channel version while OPA330 is a single channel, however, IQ is listed per channel so this does not explain the higher IQ in OPA330.  Thus, the main reason for the higher IQ, Vos, drift, etc. in OPA330 or OPA2330 is related to the fact that they are a lower cost versions of OPA333 or OPA2333, respectively, and this is achieved but shorter test times leading to higher test margins (errors), which are accounted for by increasing the max values of various parameters.

    Hello Marek,

    Thank you for your response!
    I forgot to mention that I'm interested in the DSBGA package, which has no typical value for thickness. We are interested in this typical value as we have an application with needs very low profile components. The maximum value will not do in most cases, but we can do some cherry picking ourselves as we need limited amount of components.

    I indeed thought that this increase had something to do with testing. Its good to know that we are still dealing with (more or less) the same component.

    Best regards,

    Sven

    Hi Marek,

    Could you please provide me the typical dimensions of the DSBGA package of OPA330?

    Best regards,

    Sven

    Hello Sven,

    Thanks for the question on OPA330 in our DSBGA (WLCSP) package.  For the package dimensions, please refer to the package addendum that begins on page 26.  The package drawing for the DSBGA starts at page 43. 

    The one missing dimension here is the package height which should be 575+/-30um.

    The X and Y dimensions are listed and are as follows:

    D: Max = E: Max = 1.146 mm, Min = 0.852 mm, Min = 1.086 mm 0.792 mm

    I hope this helps!
