Hi,

it's possible for DRV2667 to drive two piezo actuators in parallel.

it depends on the drive voltage and frequency.

would you please share such information from your project?

Thanks.

First of all thanks for the quick reply.

The DRV Evaluation Board DRV2667EVM-CT I need for my case study at the university. My task was to build a Hapticmodul. I bought the evaluation board, but to vibrate the power to the module is not enough. So I thought to myself, even to buy such a piezo and close in parallel with the other piezo on the board. That is why was the question of whether I can connect two identical piezo parallel?

Please excuse my english :)

many thanks

greeting

Hi, Michael:

DRV2667 is an open loop driver for Piezo (capacitance load).

DRV2667EVM-CT is designed to drive one Piezo actuator. but if the load is within DRV2667's drive capacity, it can support multiple peizo actuators.
