DRV2700 Industrial Piezo Driver

Texas Instruments DRV2700 Industrial Piezo Driver is a single-chip piezo driver with an integrated 105V boost switch, integrated power diode, and integrated fully-differential amplifier. This versatile device is capable of driving both high-voltage and low-voltage piezoelectric loads. The input signal can be either differential or single-ended and AC or DC coupled. The DRV2700 supports four GPIO-controlled gains: 28.8dB, 34.8dB, 38.4dB, and 40.7dB. The boost converter architecture does not allow the demand on the supply current to exceed the limit set by the R_(REXT) resistor which allows the user to optimize the DRV2700 circuit for a given inductor based on the desired performance requirements. Additionally, this boost converter is based on a hysteretic architecture to minimize switching losses and, therefore, increase efficiency.
