General Description
DA7280-A is a linear resonant actuator (LRA) and eccentric rotating mass (ERM) haptic driver offering automatic closed-loop LRA resonant frequency tracking.
The feature guarantees consistency across LRA production tolerances, operating temperature, aging, and mechanical coupling.
