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
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.

2.2.6 Mode 0 – Analog or Audio Input Mode 0 allows you to connect an analog input source to the DRV2667EVM-CT. See Analog/PWM Input for the hardware configuration. This shows the advantage of Piezo over other actuator technologies. Piezo actuators have a much faster response time than ERM and LRA actuators, so the Piezo actuator can be driven with an analog or audio signal and reproduce the input frequencies well. -
