Dear:

Could we use 2 or 3 DRV2667 to drive one piezo to increase driver capability?

Hi Kim,

It is not recommended to combine these drivers in parallel. If the outputs do no switch at the same exact time, then it is possible for one driver's output to be higher than the other driver and reverse bias the output FET. This could damage the device.
