    Hello,

    The resonance frequency of the actuator is 120Hz where as the LRA frequency range for DRV2605 is 125Hz - 300 Hz. Our devices also aren't really designed for actuators with such large acceleration (8G) as the BEMF would likely be too high for auto resonance tracking to work here even if the resonance was within the device range. This actuator should work with this device in open loop mode though.
