DLP651NE: Max Rotation of DMD

Babak Imangholi
Prodigy 60 points
Part Number: DLP651NE
Other Parts Discussed in Thread: DLP9000,

Tool/software:

Hello,
we want to know how much/max rotation of DMD rotate with respect to package... i found this in datat sheet

https://www.ti.com/lit/ds/symlink/dlp651ne.pdf?ts=1731522592891&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDLP651NE

 

is it going to be +/-0.8 or +/-0.4... we are using this DMD for precision optics we kindly need your confirmation ... please see below

thanks
Babak

    Hello Babak,

    I'm checking the information with the team and will get back to you with confirmation by the end of this week.

    Hi Lori,
    we discussed this internally, the hole is referenced to what? a hole is circular does not have an angle. 
    I see a better referencing to DLP9000. see below: please see note 12. we need something like that but for DLP651NE:. could you please get with your team and talk to your mechanical engineer to advise and clarify this for DLP651NE:

    Thank you

    Hi Babak,

    I'm checking with the team and please expected some days delay because the expert is out of the office.

    Hi Babak,

    It's confirmed that the active array rotation angle tolerance for DLP651NE is +/-0.8° related to the horizontal line mentioned in the figure above. 

    Our mechanical team notice the note callout on the reference active array size dimensions on sheet 3 should call out Note 2, not Note 3. Note 2 is regarding the die parallelism tolerance that is applied to the active array only that is dimensioned in Section A-A on Sheet 1.

    We will revise the mechanical drawing and make this correction on the datasheet. 

    Regards,

    Lori
