DA7280 Datasheet

DA7280 LRA/ERM Haptic Driver

DA7280 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. DA7280 offers wideban.
