Datasheet Summary
LRA/ERM Ultra-Low Power Haptic Driver with Multiple Input Triggers and Integrated Waveform Memory
General Description
DA7282 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. DA7282 offers wideband operation that fully utilizes the capabilities of newer wideband and multi-directional LRAs.
The differential output drive architecture and continuous actuator motion sensing enable efficient, calibration-free playback and minimize software plexity. Featuring wake-up...
