DRV2667 Evaluation Module

The DRV2667 is a digital interface, high-voltage driver designed to control Piezo actuators with voltages
between 40 Vpp and 200 Vpp. The DRV2667 eliminates many design complexities of driving Piezo by
including an integrated 100-Vpp boost converter and 200-Vpp differential output amplifier. In addition, the
digital control interface (I

2

C™) includes real-time waveform playback, a waveform generator, and

embedded RAM for waveform storage.

The DRV2667EVM-CT Evaluation Module (EVM) kit is a complete demonstration and evaluation platform
for the DRV2667. The kit includes a microcontroller, Piezo actuator, sample waveforms, and capacitive
touch buttons which can be used to completely demonstrate and evaluate the DRV2667.

This document contains instructions for setup and operation of the DRV2667EVM-CT, as well as an in-
depth description and examples of haptic waveforms for Piezo actuators.
