DRV2700EVM High Voltage Piezo Driver Evaluation Kit
The DRV2700 is a single-chip, high-voltage piezo driver with an integrated 105-V boost switch, integrated
power diode, and integrated fully differential amplifier. This evaluation kit demonstrates:
Multiple input modes including: 0- to 10-V single ended, PWM, and AC input modes
Multiple output modes including: 0- to 200-Vpp differential, 0- to 105-V single and multiple ended
2 power supply inputs to isolate power consumption on DRV2700
8 convenient boost voltage settings and 4 different gain settings
Small footprint (9 mm x 13 mm)
Breakout for usage as a boost converter
The evaluation kit is designed for all-around use and can be used not only for evaluation but can also be
used for prototyping into systems. The EVM also contains a microcontroller, LDO (3.3 V) and LEDs for
status and input settings.

    Figure 1 shows the names and locations of the various elements on the EVM. To power the board, connect the DRV2700EVM to an available USB port on your computer using a mini-B USB cable. The default board settings cause the microcontroller (MSP430) to control the inputs of the DRV2700 at power up. The MSP430 has each of these control settings low which disables the DRV2700, by default.
