Changes from Revision * (October 2013) to Revision A (November 2021)

  • Added and DRV2625 throughout publication.Go
  • Added general references to DRV2604 and DRV2624 throughout publication.Go
  • Updated block diagramGo
  • Added DRV2604 and DRV2624 Behave identically with the exception of having internal RAM vs ROM which does not impact the auto-resonance feature. Go
  • Added DRV2625 has same characterization but can act over a broader range of frequencies (45Hz-300Hz). Go
  • Updated the See the DRV2605EVM-CT User’s Guide or DRV2625EVM-CT User's Guide for more information. Go
  • Updated The exact resonant frequency cannot be determined empirically, because of the many environmental factors. to Users can see if device output frequency matches LRA's data sheet value but the exact resonant frequency cannot be determined entirely empirically because of the many environmental factors.
