Hi JH, Your post is being moved to the haptics forum for better support.
View ArticleForum Post: RE: LRA Motor(Linear Resonance Actuator) driving
JH, Our haptic drivers are Class D outputs. Yes, a Class D amp is okay to drive a LRA. The LRA acts as a low-pass filter, so the high frequency signal is filtered or averaged to a DC level based on the...
