OPA3693: Differential ap application layout

Part Number: OPA3693
Other Parts Discussed in Thread: DEM-OPA-SSOP-3C, DEM-OPA-SSOP-3B, DEM-OPA-SSOP-3E, DEM-OPA-SSOP-3D, DEM-OPA-SSOP-3A

In the datasheet there is a reference for an instrumentation amplifier. Is there a reference layout for this? At this bandwidth everything counts and i would like to build on existing work.

  • Hi Demian,

    have you seen the evaluation modules?

  • Hello Demian,

      We do not have a reference design specifically for that application with this device. Kai linked the unpopulated EVAL board which is a good reference for layout for this device. I would also add checking pages 25-26 in the OPA3693 datasheet for layout recommendations. I am in the process of looking for the EVAL Altium project that Kai has linked, I will get back to you with an update on that. 

    Thank you,

  • Hello Demian,

       I was able to find unpopulated EVAL board Altium projects DEM-OPA-SSOP-3A, DEM-OPA-SSOP-3B, DEM-OPA-SSOP-3E, but not DEM-OPA-SSOP-3C and DEM-OPA-SSOP-3D. All of them have the same package, but different pinouts. The closest one to C and D which Kai linked earlier, would be A. I have attached the EVM project below.
