When using a haptics driver device from the DRV26xx, DRV2700 and DRV8662 families, there are many questions around the actuator to be used. As general information, we can get some details about the supported actuators from the table below:
Depending of the user requirements, the user may select between these three actuators to develop his design. The most part of the DRV26xx family devices can change from ERM to LRA (or vice versa) with single registers modification. The piezo devices are specific for the DRV2700 and DRV8662, since they support higher capacitance and voltage values.
For more detailed questions about the recommended actuators, you may take a look at this link below. It contains information about the suggested actuators manufacturers.
TI designs contain some of these actuators with great results.
I hope this helps you!!
