Drive.P
piezoelectric sensor/actuator driver
Built around the Boréas Technologies BOS1921 driver, the advanced DRIVE.P tile provides an ultra-compact, fully-integrated solution for interfacing with piezoelectric sensors and actuators. With a maximum peak-to-peak differential output amplitude of 190V, the ability to drive one or two capacitive loads up to a total of 820nF, a built-in waveform synthesizer and high-speed 1024-sample continuous-playback FIFO, as well as a sensing resolution of just 7.6mV, this tile provides an unparalleled level of integration for next-generation haptics and other piezoactuator solutions.

Application Notes
A single piezo connected across the OUT terminals can be used for both sensing and output, including bipolar output
Two piezos can be driven by in a unipolar configuration by connecting the positive lead of each piezo to each of the OUT pads, and the negative terminals to GND. Sensing is not possible in this configuration.
