    Hi Fery,

    Yes, either device could provide haptic feedback for capacitive or resistive touch screens. The advantage of using the DRV2667 with piezo elements is that the response time is much faster (~2ms) compared to the response time of a LRA system using the DRV2605 (~20ms). Also I would recommend the DRV2625 over the DRV2605.
